2001-04-26  Pavel Roskin  <[email protected]>

       * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Use two backslashes

2001-04-11  Steven G. Johnson  <[email protected]>

       * doc/autoconf.texi (AC_F77_WRAPPERS): Mention C++ as well as C.
       In the example, don't #ifdef F77_FUNC before using it, as that
       would push any errors to link-time rather than compile-time; note
       that the user can test this to invoke alternative behavior.

2001-04-11  Akim Demaille  <[email protected]>

2001-04-10  Lars J. Aas  <[email protected]>

       * autoupdate.in (print_usage): print "\ at end of line does not

       * doc/autoconf.texi: Clean up cache documentation: Document
       --config-cache/-C option, and recommend instead of --cache-file.
       Indent example AC_CACHE_VAL macros for clarity.  Add new
       "Cache Checkpointing" section for AC_CACHE_SAVE (and
       AC_CACHE_LOAD), so that the "Cache Files" section focuses solely
       on features visible to end-users (e.g. to better fit the cross
       references).  Various minor rewordings for clarity, felicity,
       and/or grammar.

2001-04-09  Steven G. Johnson  <[email protected]>

       * doc/autoconf.texi: Revert to "configure.in" in the history, since
       "configure.ac" wasn't used in the past, and in any case it is
       probably a good idea to preserve this section verbatim.

2001-04-09  Steven G. Johnson  <[email protected]>

       * AUTHORS: Fix grammar.

2001-04-09  Lars J. Aas  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PREPARE_FS_SEPARATORS): Use `.;.' instead

       * aclang.m4 (_AC_LANG_COMPILER_WORKS): Rename as...

2001-01-24  Akim Demaille  <[email protected]>

       Don't AC_SUBST too much, as it makes Automake include those

2001-01-22  Tim Van Holder  <[email protected]>

       Simply run `testsuite' with the failed tests instead of running
       the debug scripts, this avoids having zillions of banners `Testing
       Blabla 2.13' (another means to avoid these banners is to have the
       test suite succeed :-).

2000-11-14  Paul Eggert  <[email protected]>

       * acspecific.m4 (AC_SYS_LARGEFILE): Don't worry about
       whether fseeko and ftello are properly declared.
       * acfunctions.m4 (AC_FUNC_FSEEKO): New macro, which worries about
       fseeko (and presumably ftello).  Do not set _XOPEN_SOURCE; that
       causes too many problems in practice.
       * acfunctions (fteelo, fseeko): Trigger AC_FUNC_FSEEKO.
       * doc/autoconf.texi: Adjust.

2000-11-14  Akim Demaille  <[email protected]>

2000-11-14  Akim Demaille  <[email protected]>

       * BUGS: New file.
       Be sure to read this file if you're using a non released Autoconf.
       * tests/tools.at (Syntax of the scripts): The non built tools are
       in `$top_srcdir', not `..'.
       (autoconf --trace): When using `-i' we need the src tree, not the
       build tree.

2000-11-14  Akim Demaille  <[email protected]>

       A single m4_require is enough.

       * m4sugar.m4 (_m4_require): $2 defaults to $1.

2000-11-14  Akim Demaille  <[email protected]>

       * tests/atspecific.m4 (_AT_CHECK_AC_MACRO): Don't neutralize
       autoconf's warnings.

2000-11-14  Akim Demaille  <[email protected]>

       Set AC_LANG_PREPROC_REQUIRE which replaces AC_REQUIRE_CPP.
       The main difference is that the former requires AC_LANG_COMPILER.

       * aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
       (AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
       macros.  Issue a warning when looking for the Fortran 77
       preprocessor instead of an error.
       (AC_LANG_COMPILER): Check that it is run before the corresponding
       AC_LANG_PREPROC.
       (AC_PROG_C
       (AC_LANG_COMPILER_REQUIRE): Don't call directly
       AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
       the generic code in AC_LANG_COMPILER is run.
       (AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
       (AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
       corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.


       Propagate AC_LANG_PREPROC_REQUIRE.

       * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
       AC_REQUIRE_CPP.
       * acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
       AC_REQUIRE_CPP, inner macro will do it.
       * aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
       (AC_C_PROTOTYPES): Likewise.
       (AC_C_STRINGIZE): Yeeks!  The body of AC_CACHE_CHECK was not
       quoted.  Use @%:@ do assist Emacs.


       For some reason (don't ask), this revamping revealed that
       AC_PROG_CC_STDC, because of the `break', does not clean its tmp
       files.

       * aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
       out of AC_COMPILE_IFELSE.
       Be sure to clean the tmp files.

2000-11-14  Akim Demaille  <[email protected]>

2000-11-14  Akim Demaille  <[email protected]>

       since (i) you actually need a compiler, (ii) AC_TRY_LINK handles
       it.
       * acheaders.m4 (AC_HEADER_STDC): Don't require AC_PROG_CPP,
       AC_TRY_CPP does it.

2000-11-14  Akim Demaille  <[email protected]>

2000-11-14  Akim Demaille  <[email protected]>

       Use AC_MSG_ERROR in `config.status', but adjust AC_MSG_* to use $0

       * acgeneral.m4 (AC_COPYRIGHT): s/configure.in/__file__/.
       (_AC_INIT_DEFAULTS_FDS): Append to AC_FD_LOG instead of creating
       it.  No longer insert the configure banner.

       When running

       AC_INIT
       AC_PROG_CC
       AC_LANG_COMPILER_REQUIRE

       AC_PROG_CC is expanded twice, because AC_PROG_CC provides
       `AC_PROG_CC', and not `AC_LANG_COMPILER(C)' as expected by
       AC_LANG_COMPILER_REQUIRE.

       * aclang.m4 (AC_LANG_COMPILER(C)): Instead of calling AC_PROG_CC,
       require it.

2000-11-07  Akim Demaille  <[email protected]>

       m4_syscmd was reestablished as `syscd' intead of `syscmd' because

2000-11-07  Akim Demaille  <[email protected]>

2000-11-03  Akim Demaille  <[email protected]>

       * m4sugar.m4 (m4_location): When using its value, don't use
       `m4_defn', since m4_location is not a variable, it's a macro which

2000-11-03  Akim Demaille  <[email protected]>

       * autoconf.m4: Instead of reactivating the macros before reading
       Autoconf's files, do it afterwards, so that Autoconf promotes the

       Of course this revealed numerous non updated uses of old macros in

2000-10-23  Akim Demaille  <[email protected]>

       In order to check that all the CPP symbols which are AC_DEFINE'd

       AC_DEFINE/AC_DEFINE_UNQUOTED.  Only literals can be traced, and

       macros.

2000-10-18  Morten Eriksen  <[email protected]>

       * aclang.m4 (_AC_PROG_CC_G): Use the _AC_COMPILE_IFELSE macro
       instead of reinventing the wheel. This also takes care of a bug
       where the "-g" option was accepted if the compiler silently exits
       with status unequal to 0.
       (_AC_PROG_CXX_G): Likewise.
       (AC_PROG_CC): As _AC_PROG_CC_G depends on $ac_objext and

2000-10-17  Morten Eriksen  <[email protected]>

       * acgeneral.m4 (AC_CHECK_TOOL): As AC_CHECK_PROG first tests the
       value of the VARIABLE argument when looking for executables, we
       need to set it to the correct value from AC_CHECK_TOOL when not
       just passing on the incoming VARIABLE directly.
       (AC_CHECK_TOOLS, AC_PATH_TOOL): Likewise.

2000-10-17  Assar Westerlund  <[email protected]>

2000-09-19  Pavel Roskin  <[email protected]>

2000-09-19  Pavel Roskin  <[email protected]>

2000-09-14  Pavel Roskin  <[email protected]>

       by the same reason.

       * acspecific.m4 (AC_PROG_INSTALL): Exclude c:install on AmigaOS.

2000-09-12  Akim Demaille  <[email protected]>

       The test suite fails on some hosts because for instance
         AC_INIT
         AC_CHECK_FUNC(exit)
       will not look for a compiler, it will just use `cc'.
       Macros that need a compiler should require one.

       * acgeneral.m4 (_AC_REQUIRE): New macro, which is actually the
       previous version of AC_REQUIRE plus the possibility to distinguish
       the name of the symbol being AC_PROVIDE'd, and the text to expand.
       (AC_REQUIRE): Reimplement in terms of _AC_REQUIRE.
       * aclang.m4 (AC_LANG_COMPILER, AC_LANG_COMPILER_REQUIRE)

       changes revealed the weaknesses of this macro.

2000-09-12  Pavel Roskin  <[email protected]>

       * acgeneral.m4 (_AC_TRY_CPP): New macro. It runs the preprocessor
       and checks whether it produces errors or warnings. Don't put grep
       output into a variable, use another grep instead.
       (AC_TRY_CPP): Use _AC_TRY_CPP. Copy conftest.err to config.log
       if the case of an error.
       * aclang.m4 (AC_LANG(C), AC_LANG(C++), AC_LANG(Fortran 77)):
       define AC_LANG_ABBREV to the short language name.
       (_AC_PROG_CPP_WORKS): New macro. It checks whether the current
       preprocessor can be used to check for existence of headers.
       Most code taken from ...
       (AC_PROG_CPP): ... here. Use _AC_PROG_CPP_WORKS. Use shell
       "for" to find working CPP. Use AC_LANG_PUSH(C) and AC_LANG_POP -
       it's a macro for C only.
       (AC_PROG_CXXCPP): Rewritten using _AC_PROG_CPP_WORKS.

2000-09-12  Akim Demaille  <[email protected]>

2000-09-11  Pavel Roskin  <[email protected]>

2000-09-11  Pavel Roskin  <[email protected]>

       (Autoconf Language, Quotation and Nested Macros): English fixes.
       (Quotation and Nested Macros): Unclear example replaced with
       an explanation of when m4 expands quotes. Added explanation why
       unquoted calls are dangerous.

2000-09-08  Pavel Roskin  <[email protected]>

       * doc/autoconf.texi: Always use one space before the opening
       parenthesis in @defmac.

2000-09-06  Morten Eriksen  <[email protected]>

       * acspecific.m4 (_AC_OBJEXT): No longer use AC_COMPILE_IFELSE,
       which uses $ac_objext hence depends upon _AC_OBJEXT.
       * aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call
       _AC_OBJEXT before _AC_EXEEXT since the latter needs $ac_objext.

2000-09-06  Bernard Dautrevaux  <[email protected]>

       * acspecific.m4 (_AC_EXEEXT): Set extension to void if linking
       creates both an unsuffixed file and suffixed ones.

2000-09-06  Peter Eisentraut  <[email protected]>

       * autoconf.texi: English and typo fixes.

2000-09-05  Pavel Roskin  <[email protected]>

       * acfunctions.m4 (AM_FUNC_ERROR_AT_LINE, AM_FUNC_FNMATCH,
       AM_FUNC_MKTIME, AM_FUNC_OBSTACK, AM_FUNC_STRTOD): Deactivate
       their AU_ALIAS definition: Automake 1.4 does not quote the name of
       these macros, hence when Autoconf reads Automake's definition the
       name is expanded with unpredictable results.

       takes an additional argument: action to perform when non-literal
       argument.

       * doc/autoconf.texi (Special Shell Variables): Mention it.

2000-07-10  Akim Demaille  <[email protected]>

       Set autoconf's default warnings to `syntax'.

       In fact, honor the most recent specification in the concatenation
       of `syntax',$WARNINGS,<options> in that order.

       (alflags.sed): New sub sed program.
       Compute the flags of aclocal from Makefile.am instead of
       Makefile.in, it is unlikely that aclocal be used but not automake,

2000-07-10  Akim Demaille  <[email protected]>

       * tests/atgeneral.m4 (AT_CHECK): Fix a redirection problem.

2000-07-07  Akim Demaille  <[email protected]>

       AC_REVISION must not AC_REQUIRE AC_INIT, it leaves the diversions
       in a messy state.  Don't even try to emulate AC_REQUIRE: just
       introduce a diversion just for AC_REVISION, and let the magic
       happen.
       Fixes Autoconf PR/134, from Raja R Harinath.

       * acgeneral.m4 (_AC_DIVERT(REVISION)): New diversion.
       (AC_REVISION): Don't require AC_INIT, dump in your diversion.

       Don't mess with the user variable name space.
       <ac_ld_run_path>: Prepend LD_RUN_PATH directories with -R only

       * aclang.m4 (AC_PROG_F77): Add two compilers,
       lf95 (Lahey/Fujitsu Fortran) and pgf77 (Portland Group Fortran)
       (_AC_PROG_F77_G): Some Fortran compilers produce stdout/stderr
       output even if no errors occur - check exit status rather than
       output.

2000-07-05  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_SHELL_TMPDIR): When using `mktemp -d', be sure

       Re-enable the old behavior of --host and --build.

       * acgeneral.m4 (build_alias): Set to host_alias if --build is not

       (AC_CANONICAL_HOST): Adjust help message.
       (cross_compiling): Enclose in quotes when testing.
       * aclang.m4 (_AC_LANG_COMPILER_WORKS): If cross_compiling is

       of an m4 variable to store what must be done, so that sh
       conditionals are honored.
       (_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
       _AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
       * tests/semantics.m4: Test the four AC_CONFIG sisters.

       literals, show it works properly with sh conditionals.

2000-06-26  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CACHE_VAL): Too many people put AC_DEFINE in
       the commands-to-set-it part of it.  Give them a warning.

       The current implementation of AC_REQUIRE fails on

       | AC_DEFUN([TEST2a], [])
       | AC_DEFUN([TEST2b], [REQUIRE([TEST3])])
       | AC_DEFUN([TEST3],  [REQUIRE([TEST2a])])
       |
       | AC_INIT
       | TEST1

       because it produces TEST3; TEST2a; TEST2b; TEST1.
       Fix this bug, implement the solution provided by Axel Thimm,
       and test AC_REQUIRE.

       * acgeneral.m4: Document this implementation.
       (_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
       are emitted in the same order as they are expanded.
       (AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
       particular the top level).
       * tests/base.m4 (AC_REQUIRE): New test.

2000-06-26  Akim Demaille  <[email protected]>

       A macro which is not defined with AC_DEFUN should not be

       * acspecific.m4 (AC_PROG_ECHO, _AC_DECL_YYTEXT, _AC_PATH_X_XMKMF,
       _AC_PATH_X_DIRECT): Define via `define' instead of `AC_DEFUN'.

       (AC_PATH_TOOL): Fix same bugs as in 6/9/00 fixes to AC_CHECK_TOOL.
       Pass correct arguments to AC_CHECK_PATH (different from
       AC_CHECK_PROG).  Use AC_CHECK_PATH cache variable, not
       AC_CHECK_PROG var, and use two variables for two invocations as
       above.  Quote AC_CHECK_* args.

       * acgeneral.m4 (AC_CHECK_TOOL): Even if VALUE-IF-NOT-FOUND is not
       specified, we should still check whether PROG-TO-CHECK-FOR
       actually works before returning it when the prefixed program is
       not found. Also, fixed a bug where it failed to pass the PATH
       argument in the second call to AC_CHECK_PROG.

       * Makefile.am (editsh): Transfer the names of the install
       `autoconf' and `autoheader'.
       * autoconf.sh: Add a missing period at the end of the comment

       Currently, AC_PROG_LN_S incorrectly reports yes with DJGPP. This
       is because the DJGPP `ln' emulates soft links for executables by
       generating a stub that in turn calls the real program.  This
       feature also works with nonexistent files like in the Unix
       spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
       which will attempt to call 'X.exe'. But this feature only works
       for executables.  Fix it.

       The options --build etc. used to set `$build'.  *If*

       normalized using `config.sub'.

       Now, let `--build' set `$build_alias' so that scripts with or
       without `AC_CANONICAL_BUILD' have the same semantics.  This allows
       to use `AC_CHECK_TOOL' without requiring `config.guess' and
       `config.sub' (which was bizarre anyway).

       Compute `$me' and use it in the error messages.

2000-05-03  Nicolas Joly  <[email protected]>

2000-05-03  Akim Demaille  <[email protected]>

       * tests/tools.m4 (autoheader): Don't pass `-l at_srcdir' to
       `autoheader', since `acconfig.h' is created in the build dir.
       There's one empty line less in `config.h.in' than before when

       Provide a macro to canonicalize a configuration name.
       Suggested by Ralf Corsepius.

       *  acgeneral.m4 (AC_CANONICALIZE): New macro.
       (_AC_CANONICAL_THING): Use it.


       Change the defaults for build, host, and target systems:
       build  defaults to `config.guess`.
       host   defaults to $build.
       target defaults to $host.
       Suggested by Mo DeJong, Pavel Roskin, Tom Tromey, Ian Lance
       Taylor, and many others.

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Set `$build', `$host' and
       `$target' to nothing instead of NONE.
       (AC_CANONICAL_SYSTEM): AU_DEFUN'd as `AC_CANONICAL_TARGET'.

       depending upon the THING.
       Implement the default values.
       (AC_CANONICAL_TARGET): Handle the `AC_ARG_PROGRAM' part
       `AC_CANONICAL_SYSTEM' used to provide.
       * doc/autoconf.texi: Adjust.


       When receiving an explicit argument, consider this is a default
       for --build, --host and --target (unless set).
       Some scripts might still depend on this historical syntax.
       Suggested by Alexandre Oliva.

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Do that.
       (_AC_CANONICAL_THING): Drop the support of `$nonopt'.


       Documenting --build, --host and --target when configure does not
       handle them causes confusion.
       Suggested by Pavel Roskin.
       Nevertheless configure must not die on such an `unsupported'
       option: it does happen that people build an entire tree of
       packages, some of them expecting `--host' etc. some others not.
       Stressed by Tom Tromey and Ian Lance Taylor.

       * acgeneral.m4 (HELP_CANON): New diversion.
       (_AC_INIT_PARSE_ARGS): Don't document these options.

       (_AC_ECHO, _AC_ECHO_N): Quote the call to _AC_SH_QUOTE.

       The autoheader chain needs to be adjusted.

       * acgeneral.m4 (AH_VERBATIM): Just pass two arguments to AH_OUTPUT
       instead of trying to build what `autoheader' needs: let it handle
       the format by itself.
       * autoheader.m4: Adjust.
       s,tmp/config.h,tmp/config.hin.

       The adjustment revealed that `autoconf --trace' is not robust to
       single quotes in its argument.

       * autoconf.sh: Fix this issue.
       Rename the escape `$*' as `$%'.  Implement `$@'.
       * doc/autoconf.texi: Adjust.

       mawk suffers a severe performance loss when using `sub' with a
       changing value.  On the `configure' script of the fileutils:
       mawk '{ sub (/foo/, foo++) }'                  -> 14s.
       mawk '{ if ($0 ~ /foo/) sub (/foo/, foo++) }'  -> 0.03s.
       mawk '{ sub (/foo/, foo) }'                    -> 0.03s.

       * autoconf.sh (task script, AWK script): Run `sub (__oline__,
       oline)' only in the lines that match `__oline__'.
       Suggested by Paul Eggert.

2000-04-28  Akim Demaille  <[email protected]>

       * autoconf.sh (options handling::-W*): Strip two leading chars, not

       Document --help=short and recursive.
       Split the `Directory' section into `Installation directories' for
       --prefix and --exec-prefix, and all the others into `Fine tuning
       of the installation directories'.
       In the latter, don't repeat `in DIR', the user understands, and it
       comes out better.
       Default for --exec-prefix is PREFIX.
       Reported by Kathryn Hargreaves.
       Move --host before --build.
       Fix a test on `$ac_init_help' which was not updated.

       Have `make check' succeed with CC=g++.

       * tests/atspecific.m4 (AT_TEST_MACRO): Don't check `env-after' if
       the file does not exist, which may happen when a `configure' exits

       forbids members named like their hosting struct, so don't do it.

2000-04-11  Akim Demaille  <[email protected]>

       * autoscan.pl: Reindent using 2 spaces, not 4.
       Use `#' to denote Autoconf comments, not `dnl'.

       misindentation.
       Use your base name when reporting errors.
       (parse_args::usage): Use $0, use the same order as the other
       executables.
       (parse_args): Don't dump `--help' on cmd line errors.

2000-04-11  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_PROVIDE_IF): Rename as...
       (AC_PROVIDE_IFELSE): this.  Change all callers.

2000-04-03  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): If any option waiting for a

       libexecdir, datadir, sysconfdir, sharedstatedir, localstatedir,
       libdir, includedir, oldincludedir, infodir, mandir, exec_prefix,

       Probably all the versions of bash up to 2.04 fail on
         fnmatch ("/tmp", "[/\\\\]")
       The backslash must not be last.

       * acgeneral.m4 (_AC_INIT_HELP, AC_PATH_PROG, _AC_OUTPUT_FILES,
       _AC_OUTPUT_LINKS, _AC_OUTPUT_SUBDIRS): Always make `\\' be the
       first character in all the `[]' of `case' patterns.

2000-03-27  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_CHECK_TOOL_PREFIX): Rename back as
       AC_CHECK_TOOL_PREFIX since some packages rely on it.

2000-03-27  Akim Demaille  <[email protected]>

       Move all the language dependent macros into aclang.m4.

2000-03-25  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_CANONICAL_TARGET, _AC_CANONICAL_BUILD): Rename
       as (AC_CANONICAL_TARGET, AC_CANONICAL_BUILD), although internal,
       too much foreign code depends upon them.

2000-03-25  Akim Demaille  <[email protected]>

       * autoconf.sh (translate_awk): `> "/dev/stderr"' is not portable
       to systems without a real /dev/stderr in the file system or if not
       using one of the three free awks.  Use
       print message | "cat >&2"
       ...
       END { close("cat >&2") }
       From Aharon Robbins.

2000-03-25  Akim Demaille  <[email protected]>

       (AC_TRY_LINK_FUNC, AC_CHECK_LIB, AC_CHECK_FUNC): Don't check that

       AC_LANG_SOURCE.

2000-03-21  Akim Demaille  <[email protected]>

       Fix a bug: some macros (e.g., AC_REVISION, AC_COPYRIGHT etc.) can
       be used before AC_INIT, but they do require it.  But then, the
       argument of the explicit AC_INIT call is lost.

       * acgeneral.m4 (AC_CONFIG_SRCDIR): New macro.
       (_AC_INIT_SRCDIR): Adjust.
       (_AC_INIT): Pass your argument to AC_CONFIG_SRCDIR.

       * acgeneral.m4 (AC_LANG): Renamed as _AC_LANG_CURRENT.
       (AC_LANG, AC_LANG(C), AC_LANG(C++), AC_LANG(FORTRAN77)): New

2000-03-21  Akim Demaille  <[email protected]>

       Speed ups.

       * libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
       On my machine the former implementation takes 4mn 40s to run the
       test suite.  Using m4_define leads to 4mn 15s.
       * acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
       m4_define, not define).  4mn.
       (_AC_DIVERT): Don't use m4_case.  Starting from those 4mn, if you
       just move NORMAL* first in m4_case, the test suite is run in 3mn.
       If instead of using m4, you use an `associative array' plus a
       wrapper (current implementation), it falls to 2mn.

2000-03-21  Akim Demaille  <[email protected]>

       * tests/tools.m4 (autoconf --trace): New test.

2000-03-21  Akim Demaille  <[email protected]>

       * autoconf.sh (task trace): Pipe the output of the first m4 into
       the second one, instead of saving to a tmp file, so that we can
       trace endless configure.in expansion.

2000-03-21  Akim Demaille  <[email protected]>

       Uniform idioms.

       * acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
       _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Prefer
       for i in : $is; do test $i = : && continue
       over
       for i in .. $is; do if test $i != ..; then

2000-03-21  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PREPARE, _AC_INIT_PARSE_ARGS): Move more
       initializations to...
       (_AC_INIT_DEFAULTS): here.

2000-03-21  Akim Demaille  <[email protected]>

       Give a means to compute `srcdir' earlier in configure.

       * acgeneral.m4 (_AC_INIT_SRCDIR): New macro, pulled out from...
       (_AC_INIT_PREPARE): No longer compute `srcdir'.
       (_AC_INIT): Use _AC_INIT_SRCDIR.
       (AC_INIT): Don't forget to pass the argument to _AC_INIT.

2000-03-20  Jim Meyering  <[email protected]>

       * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Don't test for existence
       of $ac_xdir.  Not only is `test -e' not portable, but the test isn't
       necessary at all;  the following mkdir ends up accomplishing the
       same goal.  Suggestion from Alexandre Oliva.

       * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT) [setting IFS]: Be careful
       to use space, tab and new line, in precisely that order.

2000-03-20  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT_SUBDIRS): Rename as _AC_OUTPUT_SUBDIRS.
       No argument, use AC_LIST_SUBDIRS.
       Adjust callers.

2000-03-20  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Double quote the head
       of the help snippet.

2000-03-20  Akim Demaille  <[email protected]>

       Give an identity to `configure' scripts.

       * acgeneral.m4 (AC_PACKAGE): New macro.
       (_AC_COPYRIGHT_SEPARATOR): Remove.
       (AC_COPYRIGHT): Adjust.
       (_AC_INIT_HELP, _AC_INIT_VERSION): Name the package you configure
       when you want.
       (_AC_INIT): Adjust.
       * configure.in (AC_PACKAGE): Add.

2000-03-20  Akim Demaille  <[email protected]>

       * acgeneral.m4: Formatting changes.

2000-03-20  Akim Demaille  <[email protected]>

       Don't rely on RS = "\0" to swallow the whole input as a single
       record, this is not portable: mawk and nawk understand it as RS =
       "".  gawk understands it as expected.

       * autoconf.sh (translate_awk::BEGIN): No longer change RS.
       (translate_awk::body): Move to the END.
       Instead, accumulate the input in `request'.

2000-03-20  Akim Demaille  <[email protected]>

       * doc/autoconf.texi (Testing Values and Files): Be a subsection of
       `Portable Shell Programming'.
       (Shell Substitutions, Limitations of Usual Tools): New subsections.

2000-03-17  Akim Demaille  <[email protected]>

       Use a single tool to reformat the raw `configure' script output by
       m4.
       Suggested by Paul Eggert.

       * autoconf.sh: Stop playing with 2 seds and an AWK to finalize
       `configure', a single AWK program is enough.

       In Autoconf 2.13, although AC_OUTPUT_COMMANDS did double quote its
       arguments, AC_OUTPUT arguments 2 and 3 were not!  Currently,
       AC_OUTPUT over quotes too: stop that.
       Reported by Martin Buchholz.

       * doc/autoconf.texi (Output): Don't expand on the ternary
       AC_OUTPUT.
       * acgeneral.m4 (AC_OUTPUT): Don't over quote $2 and $3.

2000-03-17  Joseph S. Myers  <[email protected]>

       * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Security fixes: create
       the temp files in a private temporary directory, not directly in
       TMPDIR.

2000-03-17  Akim Demaille  <[email protected]>

       Install the IFS we need once for all.

       * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.
       Handle the NLS envvars, and IFS.
       (_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.
       (_AC_WHICH_A, AC_PATH_PROG): Rely on the default IFS.
       * acspecific.m4 (AC_PROG_INSTALL, AC_FUNC_SELECT_ARGTYPES):
       Likewise.

2000-03-17  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP, AC_TRY_COMPILE,
       AC_TRY_LINK, AC_TRY_RUN_NATIVE): Simplify the removal of the
       contest files: don't remove them before running the actions, just
       remove them at the end of the macro.

2000-03-16  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use
         : ${foo='some words'}
       not
         : ${foo=some words}
       since this is not portable: Digital Unix v5.0: `bad substitution'.
       From Nicolas Joly.

2000-03-16  Lars J. Aas  <[email protected]>

       * libm4.m4 (m4_assert, m4_shiftn): New macros.
       (m4_case,m4_match): Rewrite to use m4_shiftn (for readability reasons).
       (m4_for): Add the STEP argument and some argument-verifying asserts.
       (m4_split): Correct spaces to tabulator in regexp.

2000-03-15  Akim Demaille  <[email protected]>

       Revamp AC_FUNC_SELECT_ARGTYPES.

       * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
       variable instead of three.
       Use AC_CACHE_CHECK.
       Shorten the name of the var loops, they are no longer cached.
       Include sys/types.h unconditionally.
       `select' returns an int, fixes Autoconf/46.
       Don't display parens in the user messages.

2000-03-14  Akim Demaille  <[email protected]>

       * autoheader.sh: Use run_m4f, not run_m4.

2000-03-14  John David Anglin  <[email protected]>

       * tests/actest.m4 (AC_ENV_SAVE): Don't consider RANDOM and LINENO
       which some shells update.  At least ksh on HP-UX 10.20 and sh on
       IRIX 6.5 do change their `RANDOM' even if `read' via `set'.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH): No use for @%:@ here,
       no need to over quote $1 in the comments.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4: Replace some ifelse with ifval or m4_default, or
       even nothing when not needed.
       * acspecific.m4: Likewise.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PREPARE): Insert the Autoconf version in
       config.log, and the command line which ran configure.
       Kill a couple of useless quote around dollars.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PREPARE): Kill a changequote in the
       building of `ac_configure_args'.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_DIVERT): Rename _AC_DIVERT.
       (AC_DIVERT): New macro.
       Spread its use where better than a pair of AC_DIVERT_PUSH/POP.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_BINSH): Remove, useless now that...
       (AC_REVISION): Require AC_INIT, not _AC_INIT_BINSH.
       (AC_INIT): Do what _AC_INIT_BINSH used to.
       Don't require _AC_INIT_VERSION, just call it.
       Rename as _AC_INIT.
       (AC_INIT): New macro, single expansion wrapper around _AC_INIT.
       (_AC_COPYRIGHT_SEPARATOR): New.
       (AC_COPYRIGHT): Use it.
       Require AC_INIT, not _AC_INIT_VERSION.
       * doc/autoconf.texi (Versions): Promote as first section of
       `Setup'.
       Rename as `Notices'.
       Document AC_COPYRIGHT.
       Don't give false reasons for placing AC_REVISION before AC_INIT,
       the place no longer matters.

2000-03-14  Akim Demaille  <[email protected]>

       * autoconf.sh (trace_m4::smash): Double quote, we don't want the
       result to be evaluated.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4: s/@%:@line __oline__/#line __oline__/g. __oline__
       is not a macro, so there is just no use in avoiding `#'.

2000-03-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): When there were no
       CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
       diversion, because it is AC_OUTPUT_FILES which undiverted the
       AC_SUBST sed script at its proper place, otherwise it would have
       been undiverted at the end of `configure', leading to an sh syntax
       error.
       Now that we no longer use a diversion, we don't need to call
       AC_OUTPUT_FILES if useless.
       (AC_OUTPUT_FILES): Rename as _AC_OUTPUT_FILES.
       (AC_OUTPUT_LINKS): Rename as _AC_OUTPUT_LINKS.

2000-03-14  Akim Demaille  <[email protected]>

       AC_ARG_PROGRAM must not be expanded twice, which is likely since
       Automake calls it, and usually users do too.  If it happens,
       `--program-prefix=g' actually prepend two (or more) `g'.

       * acgeneral.m4 (AC_DEFUN_ONCE): New macro.
       (AC_ARG_PROGRAM): AC_DEFUNed_ONCE.  Or is it AC_DEFUN_ONCE'd? :).
       No longer AC_EXPAND_ONCE the help string, the macro itself is
       expanded at most once.
       Rename the here-doc tag EOF_SED as EOF.

2000-03-14  Akim Demaille  <[email protected]>

       Get rid of the ICMDS diversion.

       * acgeneral.m4 (AC_DIVERT): Remove ICMDS.
       (_AC_OUTPUT_COMMANDS_INIT): New growing string.
       (_AC_CONFIG_COMMANDS_INIT, _AC_OUTPUT_CONFIG_STATUS): Adjust.

2000-03-14  Akim Demaille  <[email protected]>

       Introduce AC_SUBST(VAR, VAL).

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Stop global double quoting,
       failed experiment.
       Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
       (AC_SUBST): Implement support for 2nd arg.
       * doc/autoconf.texi (Setting Output Variables): Adjust.

2000-03-13  Akim Demaille  <[email protected]>

       Simplify the diversions naming system.
       Suggested by Alexandre Oliva and Lars J. Aas

       * libm4.m4 (ifndef): New macro.
       * acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
       its value.  The diversions now have a short name, e.g., `NOTICE',
       instead of the former macros which had long names, e.g.,
       `AC_DIVERSION_NOTICE'.
       (AC_DIVERT_PUSH): Adjust.
       (AC_DIVERT_POP): Use ifndef.
       (AC_DIVERSION_CURRENT): Rename as `AC_DIVERT_DIVERSION' to stay
       within the `AC_DIVERT' name domain.
       Adjust all callers.
       * acspecific.m4: Adjust all callers.

2000-03-13  Akim Demaille  <[email protected]>

       * doc/autoconf.texi (Invoking autoconf): Update documentation of
       `autoconf --trace'.

2000-03-13  Akim Demaille  <[email protected]>

       * autoconf.sh (tmpbase): New var.  Adjust trap code and other tmp
       file names.
       (translate_awk::BEGIN): Set RS to "\0" so that the whole file be a
       single record.
       (translate_awk::trans): Convert from array to function.
       (translate_awk::error): New function.
       (translate_awk::main action): Implement support for ${sep}@ and
       ${sep}*.  Use trans() and error().
       (translate_awk): Don't put space before user functions call, it is
       not portable.
       Remove trailing `;', this is not C :).
       (task trace): Quote `$traces' when you eval it, to protect the
       white spaces.
       Propagate `translate_awk' failures to `autoconf.sh'.
       Translate the quadrigraphs.

2000-03-13  Akim Demaille  <[email protected]>

       Trap on 0 is not executed when `exit' is called without argument.

       * autoheader.sh (trap 1 2 13 15): s/exit/exit $?/.
       * autoconf.sh: Likewise.
       Remove translate_awk too.
       * autoupdate.sh: Likewise.
       Handle `--debug'.

2000-03-13  Akim Demaille  <[email protected]>

       More uniform style in scripts.

       * autoheader.sh: s/-eq/=/.
       Uniform ordering of variable initializations, option handling.
       Don't use quotes where useless (foo=$1, not foo="$1").
       Propagate `run_m4' and `run_m4f'.
       Use `$0' in --help.
       * autoconf.sh: Likewise.
       * autoreconf.sh: Likewise.
       * autoupdate.sh: Likewise.
       * ifnames.sh: Likewise.
       * autoupdate.m4: Small bug: at the end `dnl' is disabled, so use
       `m4_dnl'.

2000-03-13  Akim Demaille  <[email protected]>

       `autoconf --trace': faster.

       * autoconf.sh (initialization): New var, new option.
       (option loop): When you need an arg, make sure there is one.
       (run_m4f): New var, which content is that of the former...
       (run_m4): Don't use m4 frozen state files.
       Change all callers.
       Don't pass AC_LOCALDIR, not documented, and unused.
       (task trace): Honor `--verbose' and `--initialization'.
       (globally): Send `--verbose' messages in stderr.
       Fix random typos.

2000-03-13  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_PROG_BINSH): Removed.

2000-03-13  Akim Demaille  <[email protected]>

       Start revamping `autoconf --trace'.

       * autoconf.sh (debug): New var, new option.
       Adjust the trap code.
       (task trace): Instead of decoding `m4 --trace' with sed, decode it
       with m4 itself.
       ($silent_m4): New file, which disables m4's `errprint'.
       ($trace_m4): New file.  Logistic for the m4 which is in charge of
       decoding the traces of the first.
       ($translate_awk): Transform a user trace request into $trace_m4
       code.

2000-03-10  Akim Demaille  <[email protected]>

       Multiple `-e' to egrep are not portable.  On IRIX 6.5 and Solaris
       2.5.1 only the last one is honored:
         > printf "foo\nbar\n" | egrep -e 'foo' -e 'bar'
         bar
         > printf "foo\nbar\n" | egrep -e 'bar' -e 'foo'
         foo
       Reported by Nicolas Joly.
       An alternative would have been to use `sed', unfortunately
       alternation is not portable.

       * tests/actest.m4 (join): New macro.
       (AC_ENV_SAVE): Join the egrep patterns into a single big one.
       * tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
       Join the egrep patterns into a single big one.

2000-03-10  Jim Meyering  <[email protected]>

       * acgeneral.m4 (_AC_CHECK_TOOL_PREFIX): Correct typos in definition:
       add `_' prefix to make the function name match comments and existing
       uses.  Remove leading prefix from _AC_CANONICAL_HOST.

2000-03-09  Ossama Othman  <[email protected]>

       * acspecific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Added some missing
       headers if they exist (needed for some missing prototypes) and
       corrects the signal handler prototype/definition.  The signal
       handler prototype is now prepended with an `extern "C"' for C++
       compilers since some platforms explicitly require an `extern "C"'
       signal handler.

2000-03-08  Akim Demaille  <[email protected]>

       * autoheader.m4 (autoheader::AC_CHECK_HEADERS_DIRENT): Rename as
       (autoheader::_AC_CHECK_HEADERS_DIRENT): to cope with the new name
       of the autoconf:: macro.
       Fixes autoconf/119, reported by Raja R Harinath.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_PATH_PROG, AC_OUTPUT_FILES, AC_OUTPUT_SUBDIRS):
       Fix quotation problems in DOS path handling.

2000-03-08  Franz Sirl  <[email protected]>

       * acspecific.m4 (AC_FUNC_MMAP, AC_FUNC_ALLOCA): Make them C++
       safe: include the right headers, cast the allocations etc.

2000-03-08  Akim Demaille  <[email protected]>

       The argument of AC_COPYRIGHT should be plain text, not an sh
       comment.

       * libm4.m4 (m4_quote): s/$@/$*/.
       * acgeneral.m4 (AC_COPYRIGHT): Prepend `# ' to the lines that go
       on the top of `configure'.  Actually, prepend `@%:@ ' so that
       there are as many evaluations on both sides.
       (_AC_INIT_VERSION): No longer strip `# '.

2000-03-08  Akim Demaille  <[email protected]>

       * tests/Makefile.am (all-local): Remove.  It wastes time to have
       testsuite rebuilt each time an ac*.m4 file changes.  It is enough
       to build it for each `make check'.

2000-03-08  Akim Demaille  <[email protected]>

       Leave a diversion exclusively for Copyright notices.

       * acgeneral.m4 (AC_DIVERSION_DEFAULTS): New diversion number.
       (_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
       here...
       (_AC_INIT_PREPARE): to here.
       (_AC_INIT_NOTICE): Play with your diversion yourself, don't let
       (AC_INIT): do it for you.
       (_AC_INIT_DEFAULTS): New macro.
       (AC_INIT): Use it.

2000-03-08  Akim Demaille  <[email protected]>

       Provide a means to specify more Copyright information in
       `configure'.  And after all, it suits to `configure --version' too.

       * acgeneral.m4 (AC_DIVERSION_DEFAULTS, AC_DIVERSION_INIT_PREPARE):
       New diversion numbers.
       (AC_DIVERSION_INIT): Rename as...
       (AC_DIVERSION_INIT_PARSE_ARGS): this.
       (AC_DIVERT_POP): Instead of going into wild endless loops when
       there are more pops than pushes, die with dignity.
       (AC_COPYRIGHT): New macro.
       (_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
       here...
       (_AC_INIT_PREPARE): to here.
       (_AC_INIT_NOTICE): Remove.
       (AC_INIT): Use it to install Autoconf's Copyright.
       (_AC_INIT_DEFAULTS): New macro.
       (AC_INIT): Use it.
       (AC_PREFIX_DEFAULTS): Dump in AC_DIVERSION_DEFAULTS.
       (_AC_INIT_PARSE_ARGS): Dump in AC_DIVERSION_INIT_PREPARE.

2000-03-08  Akim Demaille  <[email protected]>

       We don't need _AC_ARG_*_HELP_PROLOGUE.

       * acgeneral.m4 (AC_EXPAND_ONCE): AC_PROVIDE yourself, in case
       there is no AC_DEFUN associated with the text to expand.
       (_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
       _AC_ARG_VAR_HELP_PROLOGUE): Remove, instead...
       (AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): do it yourself.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Fix copy n' paste typos in
       `--with-*', `--without-*' and `*' decoding.
       Reported by Raja R Harinath.
       Fixes autoconf/118.

2000-03-08  Akim Demaille  <[email protected]>

       Don't dump AC_ARG_PROGRAM help messages if not used.

       * acgeneral.m4 (_AC_INIT_HELP): Don't.
       (AC_ARG_PROGRAM): Do.

2000-03-08  Akim Demaille  <[email protected]>

       Don't dump X help messages when `configure' does not check for X.

       * acgeneral.m4 (_AC_INIT_HELP): Don't dump X help messages.
       * acspecific.m4 (AC_PATH_X): Do it.

2000-03-08  Akim Demaille  <[email protected]>

       No longer rely on /bin/sh to compose the optional parts of
       `configure --help'.

       * acgeneral.m4 (AC_DIVERSION_HELP_BEGIN, AC_DIVERSION_HELP_ENABLE,
       AC_DIVERSION_HELP_WITH, AC_DIVERSION_HELP_VAR,
       AC_DIVERSION_HELP_END): New diversion numbers.
       (AC_EXPAND_ONCE): New macro.
       (AC_PROVIDE_IF): New macro.
       (AC_BEFORE, AC_REQUIRE): Use it.
       (AC_REQUIRE): Don't use indir.
       (_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
       _AC_ARG_VAR_HELP_PROLOGUE): New macros.
       (AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Expand once the
       _HELP_PROLOGUE macro which corresponds.
       (_AC_INIT_HELP): Adjust to AC_DIVERSION_HELP_BEGIN and
       AC_DIVERSION_HELP_END.
       (_AC_INIT_NOTICE, _AC_INIT_HELP): Remove the sh code which handled
       the optional help strings.

2000-03-08  Akim Demaille  <[email protected]>

       AC_OUTPUT_COMMANDS no longer uses a diversion.

       * acgeneral.m4 (AC_DIVERSION_CMDS): Removed.
       (_AC_OUTPUT_CONFIG_STATUS): Don't undivert it.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Fix quoted/non quoted here
       document problems.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_INIT_BINSH, AC_INIT_NOTICE, AC_INIT_PREPARE):
       Rename as...

       All callers adjusted.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_INIT_PARSE_ARGS): Rename as...
       (_AC_INIT_PARSE_ARGS): this.
       Move the display of help and version strings to...
       (_AC_INIT_HELP, _AC_INIT_VERSION): here.
       (AC_INIT): Adjust.  Also, fix quotation.

2000-03-08  Akim Demaille  <[email protected]>

       Some tests are failing with srcdir != builddir, because they can't
       find config.guess, install-sh etc.
       Reported by Erez Zadok.

       * tests/atspecific.m4 (AT_TEST_MACRO): Set AC_CONFIG_AUX_DIR to
       top_srcdir in configure.in, and pass the value of top_srcdir to
       configure.

2000-03-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH, AC_PATH_PROG,
       AC_PATH_PROGS, AC_PATH_TOOL, AC_CHECK_TOOL, AC_PREFIX_PROGRAM,
       AC_EGREP_CPP, AC_TRY_LINK, AC_COMPILE_CHECK, AC_TRY_RUN_NATIVE):
       Use ifval instead of ifelse.

2000-03-07  Mark Elbrecht  <[email protected]>

       Support absolute DOS-style paths.

       Any character before the colon is accepted because network drives
       can be assigned characters outside the [a-zA-Z] range. DOS-style
       relative paths (?:foo/bar) are also considered absolute for
       Autoconf's purposes since the path '../?:foo/bar' is invalid.

       * acgeneral.m4 (AC_OUTPUT_FILES): Treat DOS-style paths (?:*') as
       absolute.
       (AC_OUTPUT_SUBDIRS): Likewise.
       (AC_PATH_PROG): Make pattern for matching DOS-style paths the same
       as that used in AC_OUTPUT_FILES and AC_OUTPUT_SUBDIRS.

2000-03-06  Akim Demaille  <[email protected]>

       * tests/atspecific.m4 (m4_match): Remove, no longer used.

2000-03-04  Jim Meyering  <[email protected]>

       * autoheader.sh: Use `rm -f', not just `rm' when removing temporaries.
       Preserve exit status in trap handler.
       Based on suggestions from Paul Eggert.

2000-03-03  Paul Eggert  <[email protected]>

       Move the quadrigraphs out of the user name space.

       * acgeneral.m4: 's/\@BKL@/@<:@/g', 's/\@BKR@/\@:>@/g',
       's/\@DLR@/\@S|@/g', 's/\@PND@/@%:@/g'.

2000-03-03  Akim Demaille  <[email protected]>

       * acgeneral.m4 (_AC_WHICH_A): New macro.
       (AC_CHECK_PROG): Use it.  Use ifval.
       (AC_CHECK_PROGS): Use ifval.  Fix the quoting.
       * tests/semantics.m4: Test AC_CHECK_PROG.
       * tests/Makefile.am (EGREP_EXCLUDE): Add /AC_CHECK_PROGS?/.

2000-03-02  Akim Demaille  <[email protected]>

       In addition, don't dump --help on invalid options.
       * doc/autoconf.texi: Adjusted.

2000-03-02  Lars J. Aas  <[email protected]>

       * libm4.m4 (m4_noquote): New macro.

2000-03-02  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_PATH_X_DIRECT): Moved all the shell variable

       Honor properly the `#define' config.h.in templates.
       Test it.

       * acgeneral.m4 (AC_OUTPUT_HEADERS): Rename as...
       (_AC_OUTPUT_HEADERS): this.  All callers changed.
       Don't mess with changequote, just quote properly.
       Bug 1.  Because of the `#' in `ac_dA', the quotes <<>> were not
       removed, and therefore the sed script contained `<<define>>'
       instead of `define'.  Now that the block is properly quoted, there
       is no need to quote `define'.
       Bug 2.  Once a `#define' substitution performed, we were branching
       to the top of the sed script (`t top').  This resulted in an
       endless substitution of `#define foo 1' to `#define foo 1'.
       Branching is not enough: you also have to fetch the next input
       line, i.e., use `t' instead of `t t' in ac_dD, and don't output
       `: top' in `config.defines'.
       Though it was correct for `#undef' templates, just apply the same
       transformation to `ac_uD' and `config.undefs'.
       Bug 3.  Don't try to preserve what was behind the value in the
       template, since on
               #define NAME "bar baz"
       it leads to
               #define NAME 1 baz"
       Now `ac_dB' catches everything behind the NAME (making sure there
       is at least a space) and `ac_dC' only outputs a space.
       * tests/torture.m4: Check that various forms of `#define' header
       templates are properly handled.

       Avoid calling `rm' without arguments.

       * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): It is smarter to use a

       Don't rm the CONFIG_FILES here but in..
       (AC_OUTPUT_FILES) [test -n "$CONFIG_FILES"]: here.

       The AU-glue code for AC_LINK_FILES was not fully compatible: in

       there are to avoid spurious `run autoupdate' messages.
       * doc/autoconf.texi (Libraries): Document the changes.

2000-02-09  Akim Demaille  <[email protected]>

       Avoid outputting `config_files' code in `config.status' if there
       are none.

       * acgeneral.m4 (AC_OUTPUT): Don't register $1 to `AC_CONFIG_FILES'
       if $1 is empty.
       Normalize the names of the sections in `config.status --help'.

2000-02-09  Akim Demaille  <[email protected]>

       * README-alpha: New file, based on Automake's.
       * Makefile.am: Tuned.

2000-02-09  Akim Demaille  <[email protected]>

       Extend the concept of `INIT-CMDS' to the AC_CONFIG_FOOS.

       * acgeneral.m4 (_AC_CONFIG_COMMANDS_INIT): New macro which will
       collect the `INIT-CMDS'.
       (AC_CONFIG_COMMANDS, AC_CONFIG_LINKS, AC_CONFIG_HEADERS,
       AC_CONFIG_FILES): Use it, and also temporarily divert to -1
       instead of spamming dnl everywhere.
       (AC_OUTPUT_CONFIG_STATUS): Make sure to output the INIT-CMDS
       before the other sections, it'd be a pity to initialize after the
       use :).

       * doc/autoconf.texi (Configuration Actions): New section,
       documenting the common behavior of AC_CONFIG_FILES,
       AC_CONFIG_HEADERS, macro AC_CONFIG_COMMANDS, and AC_CONFIG_LINKS.

       (AC_PREREQ): Use it.

2000-02-09  Akim Demaille  <[email protected]>

2000-02-08  Akim Demaille  <[email protected]>

       Because of the names pace machinery this change makes `autoconf'
       about four times faster on complex `configure.in's.

2000-02-08  Akim Demaille  <[email protected]>

       Open the access to AH_ to users.

       All the dependencies adapted.
       * tests/actest.m4 (autoheader::AC_TATOOINE): New macro, used while
       testing autoheader.
       * tests/atspecific.m4: Create config.hin instead of config.h.in.

2000-02-08  Akim Demaille  <[email protected]>

       Because of commas and brackets, m4_split must mess with the
       quotes.

       * libm4.m4 (m4_split): Quote the elements of the list you produce.
       * tests/base.m4: New file, testing libm4.
       All callers adapted.
       Test m4_wrap.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CONFIG_UNIQUE): Strip the `:foo.in' part
       yourself, in order to give better error messages.

       changequote.
       (AC_OUTPUT_SUBDIRS): Likewise.

2000-02-08  Akim Demaille  <[email protected]>

       * autoupdate.sh: Don't dump --help on --wrong-option.
       * autoconf.sh: Reformatting, and use >&2 instead of 1>&2.

       the common behavior of the macros.
       (Standard Symbols): New subsection.  Describes the transformation
       of the AC_DEFINEd names.
       (Default Includes): New subsection.  Obvious content.
       All the ``callers'' updated.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT_HEADERS): Don't use `break' to exit the
       while loops which are breaking conftest.defines and
       conftest.undefs into smaller snippets: just use the proper
       condition for the while.
       Suggested by Alexandre Oliva.

2000-02-08  Akim Demaille  <[email protected]>

       * doc/autoconf.texi (Configuration Commands): New section, for
       AC_CONFIG_COMMANDS.

       (Configuration Links): New section, for AC_CONFIG_LINKS and
       AC_LINK_FILES.
       (Configuration Files): New section, for AC_CONFIG_FILES.

       (Using System Type): Don't document AC_CONFIG_LINKS and
       AC_LINK_FILES.
       (Invoking config.status): Mention CONFIG_COMMANDS.
       Document --file and --header.
       Talk first of the newest interface of config.status.

2000-02-08  Akim Demaille  <[email protected]>

       Introduce a concept index, and update a bit the documentation.

       * doc/autoconf.texi (Concept Index): New section.
       Various entries added.
       (Typedefs): Rename as...
       (Types): this.  Pay attention to not limiting the documentation to
       the typedefs.
       (Particular Types): Mention the equivalent generic test.
       Promote the GNU coding style at various places.

2000-02-08  Akim Demaille  <[email protected]>

       Revamp the autoupdate/AC_OBSOLETE chain.  All the details are
       given in the prologue of acoldnames.m4.

       * acgeneral.m4 (Prologue): Enter the `autoconf' name space.
       (AU_DEFUN): New macro.

       * autoupdate.m4: New file.
       Disable the name spaces `autoconf', and `libm4'.  Disable libm4.
       * Makefile.am: Tuned to support the changes above.

       * autoupdate.sh: Model after autoconf.sh.
       Can run on several files at once (for instance m4/*.m4).
       Don't touch files that are up to date.
       Run m4 on autoupdate.m4f instead of playing with sed.


       Use AU_DEFUN.

       * acgeneral.m4 (AC_LINK_FILES, AC_ENABLE, AC_WITH): Use AU_DEFUN,
       remove the call to AC_OBSOLETE.
       * acspecific.m4 (AC_CYGWIN32): Likewise.
       * acoldnames.m4: Replaced all the definitions via `define' or
       `AC_DEFUN' to use `AU_DEFUN'.

2000-02-08  Akim Demaille  <[email protected]>

       Clean up some m4 files.

       * acoldnames.m4: Use `#', not `dnl'.
       Don't spread `dnl' everywhere, anyway, we are in a divert(-1).
       * autoconf.m4: Likewise.
       * autoheader.m4: Likewise.

2000-02-08  Akim Demaille  <[email protected]>

       Clean up autoconf.

       * autoconf.sh: Minor reorganizations to clearly separate the
       prologue, which is almost common to all the shell scripts of
       Autoconf, and the body.

2000-02-08  Akim Demaille  <[email protected]>

       Improve support of name spaces in libm4.  Put the m4 builtins
       in the `libm4' name space.

       * libm4 (m4_changequote, m4_define, m4_defn, m4_dnl, m4_indir,
       m4_undefine): Private copies in the global name space.  Used by
       the name space mechanisms.
       (m4_namespace_register): New macro.
       (m4_namespace_define): Use it.
       (builtin, changequote, defn, dnl, esyscmd, ifdef, ifelse, indir,
       patsubst, popdef, pushdef, regexp, undefine, syscmd, sysval): Put
       in the `libm4' name space.
       (m4_disable, m4_enable): Use the private m4_indir, otherwise once
       `libm4' closed, there is no `indir' available, and therefore no
       means to reopen a name space.

2000-02-08  Akim Demaille  <[email protected]>

       Output really nothing if AC_INIT was not given.  Unconditional
       output can be problematic with autoupdate.

       * acgeneral.m4 (AC_INIT_NOTICE): Output ac_includes_default.
       (Default includes section): No longer dump ac_includes_default in
       AC_DIVERSION_INIT.

2000-02-08  Akim Demaille  <[email protected]>

       * libm4.m4 (m4_namespace_define): Fix a bug: `m4_namespace'
       instead of `$1'.
       Simplify some excess in quoting.
       Use NAMESPACE::MACRONAME instead of `m4_defn(NAMESPACE,
       MACRONAME)'.

2000-02-08  Akim Demaille  <[email protected]>

       Adapt autoheader to use libm4's name spaces.

       * autoheader.m4 (AH_HOOK): Removed.
       (AH_DEFUN): Define in the `autoheader' name space.
       Use only AH_DEFUN to define macros in this file.
       (epilogue): No longer run the `AH_HOOKS', enter the `autoheader'
       name space.

2000-02-08  Akim Demaille  <[email protected]>

       Clean up a bit the user interface.

       * autoconf.sh: Give your name while reporting errors.
       Don't spit --help for errors on arguments.
       * autoreconf.sh: Likewise.
       * autoheader.sh: Likewise.
       More temporary files that one can browse when debugging.
       Don't ${var}, just $var.
       Don't dump --help when the arguments are invalid.
       (config_h): Use the empty value instead of `undefined' to check
       that it is defined.
       * acspecific.m4: Formatting changes.

2000-02-08  Akim Demaille  <[email protected]>

       Introduce name spaces in libm4.

       * libm4.m4 (m4_namespace_push, m4_namespace_pop,
       m4_namespace_define, define, m4_disable, m4_enable, m4_rename):
       New macros.
       (_m4_foreach, _m4_for, m4_wrap): Use m4_define for temporaries.
       (m4_split): Don't mess with the quotes.

       * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS, AC_OUTPUT_HEADERS): Quote
       `define'.

2000-02-08  Akim Demaille  <[email protected]>

       * doc/autoconf.texi (Introduction): m4 1.4 is now required.
       (Invoking autoconf): A better help on --trace.
       (Defining Symbols): Advocate a proper use of the quotes in m4
       code, including if the quotes are sometimes useless.  It is bad,
       very bad not to quote properly, so quote all the examples
       properly.
       (Cache Files): Use a unary call to define, instead of an empty
       $2.
       (Using System Type): Watch out TeX wrapping.
       (Pretty Help Strings): Don't give too long a snippet of --help.
       Promote the coding style of Autoconf.  Quote properly.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_PRO): Use AC_PROVIDE instead of defining
       yourself.  This allows to see everything that is AC_PROVIDEd via
       autoconf --trace.
       (AC_SPECIALIZE): define'd, not AC_DEFUN'd.
       (AC_PROVIDE): Use define with a single arg, instead of an empty $2.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (ac_includes_default): Don't use simple quotes, but
       doubles quotes if you want to use \-continuation lines: this is
       not recognized by MIPS' sh.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4. Formatting changes.
       * acspecific.m4: Likewise.

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CONFIG_HEADERS, AC_CONFIG_LINKS,
       AC_CONFIG_SUBDIRS): A space was missing to separate the arguments
       of m4_append.

2000-02-08  Akim Demaille  <[email protected]>

       Arrange that config.status creates the file with the AC_SUBSTing
       engine only if needed.

       * acgeneral.m4 (AC_OUTPUT_FILES): Create the sed code only if test
       -n "$CONFIG_FILES".

2000-02-08  Akim Demaille  <[email protected]>

       Promote AC_LANG_CASE.

       * acgeneral.m4 (AC_TRY_COMPILER, AC_TRY_LINK_FUNC, AC_CHECK_LIB,
       AC_TRY_COMPILE, AC_TRY_LINK, AC_TRY_RUN_NATIVE, AC_CHECK_FUNC):
       Use AC_LANG_CASE instead of ifelse (AC_LANG, ...).
       (AC_TRY_LINK_FUNC): Quote the body the the AC_DEFUN (whoa, how
       could this survive so long?!?).

2000-02-08  Akim Demaille  <[email protected]>

       * acgeneral.m4: Formatting changes.
       * acspecific.m4: Likewise.

2000-02-08  Akim Demaille  <[email protected]>

       Use the style we promote.

       * doc/autoconf.texi (Header Templates): Promote #if over #ifdef;
       and #undef over #define in templates.
       * acspecific.m4 (AC_DECL_SYS_SIGLIST, AC_FUNC_MMAP,
       AC_FUNC_SETPGRP, AC_FUNC_VFORK, AC_FUNC_SELECT_ARGTYPES): Use #if,
       not #ifdef and #ifndef, indent CPP directives.

2000-02-08  Akim Demaille  <[email protected]>

       Quote properly AC_SHELL_IFELSE and callers.

       * acgeneral.m4 (AC_SHELL_IFELSE): Don't overquote $1.
       (AC_VAR_IF_SET, AC_CHECK_MEMBER, AC_CHECK_LIB, AC_CHECK_HEADER,
       AC_CHECK_DECL, AC_CHECK_FUNC, AC_CHECK_TYPE_INTERNAL): Quote the
       first argument of AC_SHELL_IFELSE.

2000-02-08  Akim Demaille  <[email protected]>

       It seems quite delicate to have AC_INCLUDES_DEFAULT insert the
       default headers in the INIT section of configure: the reason is
       that AC_INCLUDES_DEFAULT is called unquoted, and this results in
       an un expected behavior.  Thanks to Roman V. Shaposhnick for the
       details.

       The current implementation is not satisfying: the default headers
       are defined in the INIT section even if they are not used.

       * acgeneral.m4 (Prologue of AC_INCLUDES_DEFAULTS): Dump the
       definition of ac_includes_default in the INIT section of
       configure.
       (AC_INCLUDES_DEFAULTS): Use it.

2000-02-08  Akim Demaille  <[email protected]>

       Rename f77_link_output as ac_link_output.
       * tests/actest.m4 (AC_ENV_SAVE): Don't note F77, FFLAGS, FLIBS,
       G77, f77_case, f77_underscore.

2000-02-07  Akim Demaille  <[email protected]>

       * libm4.m4: here.
       * acgeneral.m4 (AC_WRAP): Moved from here, to...

       * autoconf.m4: Include libm4.m4 and acversion.m4.
       * autoheader.m4: Likewise.

2000-02-07  Akim Demaille  <[email protected]>

       AC_CHECK_SIZEOF: Fix a bug, use standard default headers, and
       test.

       * acgeneral.m4 (AC_CHECK_SIZEOF): Don't over quote $1, some []
       were left in the C code, and had the macro fail.
       Use AC_INCLUDES_DEFAULT.
       * doc/autoconf.texi: Mention default includes.  Explain stdio.h
       must always be given.

2000-02-07  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): Instead of defining an
       unused pointer to the type $1, use
       if (($1 *) 0) return 0;
       to avoid warnings from the compiler.
       From Paul Eggert.

2000-02-07  Akim Demaille  <[email protected]>

       Reported by Jim Meyering.

       nor /^AC_PROG_\(CC\|CXX\|F77\)_\(GNU\|WORKS\)$/: they are already
       tried elsewhere.
       * tests/Makefile.am: Adjusted.

2000-02-07  Akim Demaille  <[email protected]>

       but ac_save_FFLAGS.
       (AC_F77_NAME_MANGLING): Don't use foo_bar but ac_foo_bar.

2000-02-07  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_C_INLINE): Proceed as for AC_C_CONST:
       condition out the test case if __cpluscplus.
       Don't document the autoheader template twice, one is enough.
       * autoheader.m4 (AC_CONFIG_HEADER): don't hook on this guy, but
       on...
       (AC_CONFIG_HEADERS), since the former is defined on the latter.

2000-02-07  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): Use the scheme proposed
       by Alexandre Oliva for testing the definition of TYPE:

       * tests/syntax.m4 (TEST_MACRO): Don't run AC_ARG_VAR.
       Reported by Jim Meyering.
       Use AT_CASE.

2000-02-07  Akim Demaille  <[email protected]>

       Test that the macros respect the user variable name space.

       * acgeneral.m4 (AC_CANONICAL_THING): define, not AC_DEFUN.
       Don't AC_PROVIDE, there is no need.
       When calling `config.sub`, also || exit 1, to catch failures from
       config.sub.
       * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Use ac_val, not val.
       (AC_EXEEXT): Use ac_file, not file.
       * tests/actest.m4: New file, holding extra Autoconf macros used
       during the testing.
       (AC_ENV_SAVE): New macro, save the sh variables in a file.
       * tests/suite.m4 (AT_TEST_MACRO, Generation of configure.in):
       include actest.m4, and call twice AC_ENV_SAVE to compare the
       variables before and after the macro.
       * tests/Makefile.am (macro.m4): Don't test macros that are
       required: they will be tested somewhere else.

2000-02-07  Akim Demaille  <[email protected]>

       * acgeneral.m4(AC_CONFIG_PRE_COMMANDS, AC_CONFIG_POST_COMMANDS):
       Rename as AC_CONFIG_COMMANDS_PRE, AC_CONFIG_COMMANDS_POST.  All
       dependencies changed.
       From Jim Meyering.

2000-02-07  Akim Demaille  <[email protected]>

       * acgeneral.m4: Formatting changes.
       * acspecific.m4: Likewise.

2000-02-07  Akim Demaille  <[email protected]>

       Start a new series of tests which check the semantics.

       * acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
       ac_Foo, and use AC_Foo.  Got rid of AC_Member_Aggregate and
       AC_Member_Member which were complicating more than simplifying.
       (AC_CHECK_DECLS): Use m4 lists.
       (AC_CHECK_TYPES): A comma was missing.
       * autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
       * doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
       lists.
       * tests/semantics.m4: New file.  Collection of semantical tests:
       verify that the tests are positive and negative when appropriate.
       Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.

2000-02-04  Akim Demaille  <[email protected]>

       * tests/Makefile.am (macros.m4): Fix the sed snippet.

2000-02-04  Akim Demaille  <[email protected]>

       * testsuite/autoconf.g/init.exp: Removed, test performed by
       tests/syntax.m4.
       * testsuite/autoconf.g/sizeof.exp: Likewise.
       * testsuite/autoconf.s/defines.exp: Likewise.
       * configure.in (AC_OUTPUT): Adjusted.
       * Makefile.am (SUBDIRS): Adjusted.

2000-02-04  Akim Demaille  <[email protected]>

       * tests/syntax.m4: Test AC_CHECK_SIZEOF.
       * tests/Makefile.am (CLEANFILES, DISTCLEANFILES): Adjusted.
       (macros.m4): Use tmp dest files ($@-t), not directly `$@'.

2000-02-04  Akim Demaille  <[email protected]>

       Hide AH_HOOK behind AH_DEFUN.

       * autoheader.m4 (AH_DEFUN): New macro.  Combination of define and
       AH_HOOK.
       (AC_TRY_RUN, AC_DEFINE, AC_DEFINE_UNQUOTED, AC_CHECK_LIB,
       AC_CHECK_HEADERS, AC_CHECK_HEADERS_DIRENT, AC_CHECK_DECLS,
       AC_CHECK_FUNCS, AC_CHECK_SIZEOF, AC_PROG_LEX, AC_CHECK_MEMBERS,
       AC_CHECK_TYPE, AC_FUNC_ALLOCA, AC_CHECK_TYPES, AC_C_CHAR_UNSIGNED,
       AC_AIX, AC_F77_WRAPPERS, AC_CONFIG_HEADER): All the former calls
       to define and AH_HOOK in autoheader.m4 are replaced by AH_DEFUN.

2000-02-04  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_RSH, AC_ARG_ARRAY, AC_HAVE_POUNDBANG): No use
       to hide, you are DEFUNCT.

1999-11-14  Akim Demaille  <[email protected]>

       * autoconf.texi (Invoking ifnames): ifnames no longer supports
       --macrodir.

1999-11-13  Akim Demaille  <[email protected]>

       Run the `syntax' test on acgeneral macros too.
       Fix the bugs discovered.

       * acgeneral.m4 (AC_CANONICAL_THING): Quote the
       AC_REQUIRE([AC_CANONICAL_HOST]).  Bug triggered by the use of
       AC_CANONICAL_BUILD alone in configure.in.  Also, quote the
       arguments of macros (eg, ifelse([$1]...), not ifelse($1...)).
       (m4_case): New macro.
       (AC_LINKER_OPTION): Don't clash with user's name space
       (s/i/ac_link_opt).
       (AC_LIST_MEMBER_OF).  You mean AC_FATAL, not AC_MSG_ERROR.
       Quote properly the argument.
       dnl out the empty lines that result from m4 pure code.
       Don't pollute the user name space.
       Use AC_SHELL_IFELSE.
       (AC_F77_NAME_MANGLING): Don't use `test -o'.  There are still
       name space problems.
       * tests/Makefile.am (macros.m4): Also fetch the macros from
       acgeneral.m4.

1999-11-13  Akim Demaille  <[email protected]>

       Really install this patch.

       * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
       optional $2: exit status.

1999-11-13  Akim Demaille  <[email protected]>

       Check that the AC_DEFINEs from acspecific.m4 do have a template.
       Fix the discovered bugs.

       * tests/atgeneral.m4 (AT_CHECK): Don't just exit 1 when you want
       to propagate the failure of a test: exit with the same exit
       status, at least to preserve 77 (=ignore).
       * tests/syntax.m4 (TEST_MACRO): Run also autoheader.  Don't run
       this test on all the macros, some just cannot run without
       arguments.
       * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): In the if egrep/fi for
       #define templates, add a `:' to prevent syntax errors in
       config.status when there are no AC_DEFINE performed.
       * autoheader.m4 (AH_TEMPLATE): Don't use _AC_SH_QUOTE here, use it
       in...
       (AH_VERBATIM): here.  Now AH_C_UNSIGNED_CHAR is no longer failing
       (formerly it would produce a non backslashed backquote, which
       made sh choke).

1999-11-13  Akim Demaille  <[email protected]>

       Introduce a means to distinguish failures of `configure' due to
       extern software (so that the test suite doesn't fail on them).

       * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
       optional $2: exit status.
       * doc/autoconf.texi: Document.
       * acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
       AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.

1999-11-13  Akim Demaille  <[email protected]>

       Clean up a bit the handling of the LANG stack.  More is needed.

       * acgeneral.m4 (AC_LANG_CASE): New macro.
       (AC_LANG_RESTORE): Use m4_case.
       (AC_LINKER_OPTION): Use AC_LANG_CASE.

1999-11-11  Akim Demaille  <[email protected]>

       * autoconf.texi (Generic Declarations): Fixed a typo which
       prevented `make distcheck' from succeeding.
       * texinfo.tex: Updated for the same reasons.

1999-11-11  Akim Demaille  <[email protected]>

       Introduce a new style of testing, independent from DejaGNU.


       Introduce the logistics.

       * configure.in: Initialize AT, and output tests/atconfig, and
       tests/Makefile.
       * m4/atconfig.m4: New file.
       * m4/Makefile.am: Adjusted.
       * aclocal.m4: Include atconfig.m4.

       * tests/Makefile.am: New file.
       * tests/atgeneral.m4: Likewise.
       * tests/atconfig.in: Likewise.


       Write tests.

       * tests/syntax.m4: New file, in charge of checking the validity of
       the sh code produced by the macros defined in acspecific.m4.
       acgeneral.m4 is not checked here, because these macros require
       arguments.
       * tests/suite.m4: New file.  Run syntax.m4.

1999-11-10  Akim Demaille  <[email protected]>

       A test suite will be introduced which tries to run all the
       specific macros, but hasbeen'd macro make configure die with bad
       exit status.  So we wish to distinguish live macros from defunct
       macros at the moment they are AC_DEFUN'd, not in their body.  Hm,
       defunct, defunct... Hey!  That's a good name!

       * acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
       but for macros which are no longer defined.  Replaces AC_HASBEEN.
       (AC_HASBEEN): Defunct.  Well, removed in fact.
       (AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
       AC_DEFUNCT.
       * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
       AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
       (AC_XENIX_DIR): It was defunct even before I declared it was: was
       depending upon AC_DIR_HEADER which is defunct.  So AC_DEFUNCT'ed
       now.
       (AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
       too are defunct now.
       * autoconf.texi (Obsolete Macros): Replace the documentation of
       AC_HASBEEN with that of AC_DEFUNCT.

1999-11-10  Akim Demaille  <[email protected]>

       * autoconf.sh: Formatting changes.
       Removed development junk.
       * acspecific.m4: Formatting changes.
       * autoconf.m4: Likewise.
       * autoheader.m4: Likewise.

1999-11-10  Akim Demaille  <[email protected]>

       Let Autoconf use autoconf's `--install'.

       * m4/Makefile.am: New file.
       * m4/init.am: New file, required by Automake.
       * m4/missing.am: Likewise.
       * m4/sanity.am: Likewise.
       * aclocal.m4: Include them.
       * configure.in (AC_OUTPUT): Added m4/Makefile.

1999-11-10  Akim Demaille  <[email protected]>

       Make autoconf support --install.

       * autoconf.sh (task install): New task.  Extract the set of
       auxiliary m4 files a configure.in depends upon.  Install links
       from library files to the local dir so that the packages depends
       only on local extensions.  Check that the user includes exactly
       the files she needs.

1999-11-10  Akim Demaille  <[email protected]>

       Require GNU m4 1.4 (well 1.3 in fact).

       Because we are ready to handle the case where there are no frozen
       files, we *have* to pass a -I, which is dangerous in conjunction
       with the silent including of `aclocal.m4': you may include things
       that were not expected.  Since anyway handling pre 1.3 complicates
       the task, just require an m4 which supports reloading of frozen
       files.

       * acspecific.m4 (AC_PROG_GNU_M4): Check for --reload.
       * autoconf.sh: Likewise
       * autoheader.sh: Likewise.
       * configure.in: Explicitly state the m4 version you want.

1999-11-10  Akim Demaille  <[email protected]>

       No need for foo="`bar`", foo=`bar` is fine.
       Simplify ${foo} and ${1} into $foo and $1.

       * acgeneral.m4 (ac_LF_and_DOT): Remove the double quotes.
       * acspecific.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Likewise.
       * autoconf.sh: Likewise.
       * autoheader.sh: Likewise.
       * autoreconf.sh: Likewise.
       * autoupdate.sh: Likewise.
       * ifnames.sh: Remove all the code and messages related to
       AC_MACRODIR, since ifnames is not related to macros in anyway.

1999-11-10  Akim Demaille  <[email protected]>

       New version of AC_INCLUDE, which does not glob, nor rely upon the
       shell.  Add AC_INCLUDES too.  Help tracking multiple inclusions.

       * acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
       variations around errprint.
       (m4_include_unique): New macro which registers what are the files
       already included, and warns if some are included several times.
       (m4_include, m4_sinclude): New macro, using m4_include_unique.
       (AC_INCLUDE): Is now just a wrapper of m4_include.
       (AC_INIT): Use m4_sinclude, not sinclude.
       (_AC_ERRPRINT): Removed, m4_errprint is here!
       (AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.

1999-11-01  Akim Demaille  <[email protected]>

       * autoheader.sh: No longer rely on a system acconfig.h.

1999-11-01  Akim Demaille  <[email protected]>

       Be kind to Automake: list the arguments of selected macros
       (for instance AC_SUBST will list each variable which may be
       substitued).

       * autoconf.sh (--trace, --output): New options.
       Implement tracing of macros.
       trap also on 0, so that there is no need to rm here and there.
       * autoconf.texi (Output): Document --trace and --output.

1999-11-01  Akim Demaille  <[email protected]>

       Clean up the macros for testing members of aggregates.

       * acgeneral.m4 (AC_CHECK_MEMBER): FATAL if $1 has no dot in it.
       Use AC_INCLUDE_DEFAULTS.
       (AC_C_STRUCT_MEMBER): Removed.
       * acspecific.m4 (AC_STRUCT_TIMEZONE): Adapted to AC_CHECK_MEMBERS.
       (AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Adapted to
       AC_CHECK_MEMBERS and obsoleted.
       (AC_STRUCT_ST_BLOCKS): Adapted to AC_CHECK_MEMBERS.
       * autoconf.texi (AC_STRUCT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_RDEV):
       Explain they are obsoleted, and how to migrate.
       (AC_STRUCT_ST_BLOCKS, AC_STRUCT_TIMEZONE): Explain that the
       AC_DEFINE changed (but the former #defines remain defined
       currently).
       (AC_C_STRUCT_MEMBER): Removed, replaced by the definitions of
       AC_CHECK_MEMBER and AC_CHECK_MEMBERS.

1999-11-01  Akim Demaille  <[email protected]>

       Install a uniform set of default includes.

       * acgeneral.m4 (AC_INCLUDES_DEFAULT): New macro.  Expands in its
       argument if non empty, otherwise a default list of includes.
       (AC_CHECK_DECL, AC_CHECK_TYPE_INTERNAL): Use AC_INCLUDES_DEFAULT.
       * autoconf.texi: Adjusted.

1999-11-01  Akim Demaille  <[email protected]>

       * autoheader.m4 (AH_FUNC_ALLOCA, AH_C_CHAR_UNSIGNED, AH_AIX):
       Don't leave `[]dnl' in pseudo #-comment (actually CPP directives).

1999-11-01  Akim Demaille  <[email protected]>

       Fix a bit of the brokenness of AC_CHECK_TYPE.

       * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
       the former AC_CHECK_TYPE.  This macro is exactly the one that
       ought to be named AC_CHECK_TYPE: it just checks, and executes user
       actions.  In the future, this macro ought to be renamed
       AC_CHECK_TYPE.
       There is a big difference with the former AC_CHECK_TYPE: instead
       of grepping in the headers, it tries to compile a variable
       declaration.  This is both safer, slower, and better, since now we
       can check for compiler types (e.g., unsigned long long).
       (AC_CHECK_TYPES): The looping and AC_DEFINEing version of the
       previous macro.  Uses m4 loops.
       (AC_CHECK_TYPE): Reimplemented on top of AC_CHECK_TYPE_INTERNAL.
       * autoheader.m4 (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros,
       hooked.
       * autoconf.texi (@ovar): New macro, for optional variables.
       (Generic Typedefs): Document AC_CHECK_TYPES.
       * autoheader.texi: (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros.
       (Epilogue): Hooks them.

1999-11-01  Akim Demaille  <[email protected]>

       Update autoupdate.

       * acoldnames.m4:  Sort the two sections.
       * acoldnames.m4 (AM_CYGWIN32, AM_EXEEXT, AM_FUNC_FNMATCH,
       AM_FUNC_MKTIME, AM_PROG_LIBTOOL, AM_MINGW32, AM_PROG_INSTALL,
       fp_FUNC_FNMATCH): Added their new names.

1999-10-31  Akim Demaille  <[email protected]>

       Create man pages for the executables.

       * Makefile.am (SUBDIRS): Add `man' and prepend `.' so that
       executables be built before help2man is run.
       * configure.in (AC_OUTPUT): Add man/Makefile.
       AC_MSG_ERROR, not AC_ERROR.
       Check for missing help2man.

       * acgeneral.m4: Formatting changes.

       commands to run, as AC_CONFIG_FILES and HEADERS.
       (AC_LIST_LINKS_COMMANDS): New growing string.  Initialize.
       (AC_OUTPUT_LINKS): Use it.
       (AC_OUTPUT_FILES, AC_OUTPUT_HEADERS, AC_OUTPUT_LINKS): Don't

1999-10-31  Akim Demaille  <[email protected]>

       (_AC_ECHO): Quote properly the argument.
       (AC_TRY_RUN): Don't quote [AC_TRY_RUN] in the warning.

1999-10-31  Akim Demaille  <[email protected]>

       AC_ARG_WITH, AC, TRY_COMPILER, AC_TRY_RUN, AC_TRY_CPP,
       AC_EGREP_CPP): Use @PND@ instead of [#]: it looses the editors

       Formatting changes.

       * acspecific.m4 (AC_PROG_GNU_M4): New macro.
       * configure.in: Use it.

1999-10-31  Akim Demaille  <[email protected]>

       Provide a means to specify commands to run before config.status is
       created (and, for symmetry, after it is created).

       This is typically needed by Automake so that AC_REPLACEd functions
       go through deansification via

       LIBOBJS=`echo $LIBOBJS | sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`

       and/or by Libtool which needs to define LTLIBOBJS and others:

       LTLIBOBJS=`echo $LIBOBJS | sed 's/\.o/\.lo/g'`
       AC_SUBST(LTLIBOBJS)

       * acgeneral.m4 (AC_OUTPUT_PRE_COMMANDS): New growing string.
       Initialize.
       (AC_OUTPUT_POST_COMMANDS): Likewise.

       (AC_CONFIG_PRE_COMMANDS): Likewise.
       (AC_OUTPUT): Run AC_OUTPUT_PRE_COMMANDS before
       AC_OUTPUT_CONFIG_STATUS, and AC_OUTPUT_POST_COMMANDS after.

1999-10-31  Akim Demaille  <[email protected]>

       Remove spurious empty lines appearing in configures.

       * acgeneral.m4 (AC_CONFIG_UNIQUE): Produce no output.  Instead of
       fighting with dnl, divert to KILL upon entry, and pop at exit.

1999-10-31  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_INIT_PARSE_ARGS): Avoid using double quotes
       inside "`...`": some shells parse this incorrectly.

1999-10-31  Akim Demaille  <[email protected]>

       * Makefile.am (pkgdata_DATA, EXTRA_DIST): Removed acconfig.h.
       * testsuite/autoconf.s/defines.exp: Commented out, there is no

       Create AC_CONFIG_HEADERS which has the same interface as the other
       AC_CONFIG_*S.

       * acgeneral.m4 (AC_CONFIG_HEADERS): New macro, with the same
       interface as AC_CONFIG_LINKS and AC_CONFIG_FILES.
       (AC_LIST_HEADERS_COMMANDS): New growing string, initialize it.
       (AC_CONFIG_HEADER): Rename as...
       (AC_CONFIG_HEADERS): this, for consistency.
       (AC_CONFIG_HEADER): New macro, which calls AC_OUTPUT_HEADERS.
       (AC_OUTPUT_HEADERS): The square brackets for sed and grep were
       not properly quoted: use @BKL@ and @BKR@.
       (AC_OUTPUT_HEADERS): Run the AC_LIST_HEADERS_COMMANDS.

       * acgeneral.m4 (AC_OUTPUT): Once config.status created, before
       running it, trap to `exit 1' so that config.status is not removed
       if configure is interrupted when config.status is complete.

       * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): When recognizing
       arguments, accept only foo, and no longer foo:foo.in etc.

       config.status: Speed up the creation of config headers (about four
       times faster on Linux).

       The previous scheme had three sed commands for each AC_DEFINE: one
       for #define templates, and two for #undef templates (with or
       without trailing spaces).  Divide this in three sed scripts
       instead: a one liner that removes the trailing spaces, one for
       #defines, and then the last for #undef.

       The real speed up comes from the fact that the #define script
       starts by checkin if the current input line has a #define, and if
       not the script immediately goes to the next line, without running
       the rest of the script as was the case before.  Equally for the
       #undef script.

       Note that this way, users that don't use #define templates don't
       pay too much the overhead, since the sed script `realizes' quickly
       there are no #define lines.  My test case runs in 0.32s with
       #define templates, and 0.24s without.  To improve this common
       case, the whole code for #define templates is conditionalized by a
       proper egrep call.  The result runs is 0.24s, i.e., almost no cost
       at all.

       I made one dangerous change that I carefully evaluated before
       commiting: the sed scripts are cut at 48 lines instead of 12 as
       before.  This produces here docs of about 4Kb.  I checked many
       `configure's and they all have big here documents, much bigger
       than the 12 lines (for instance AC_FUNC_MMAP produces a 150 lines
       long, 3800+ character here document).  So I moved to the well
       known HP UX sed limitations: no more than 100 commands, and there
       are two commands per line now, plus a two command preamble.  The
       speed up is noticeable.

       * acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e
       family.
       Changed ac_uD and ac_dD to `...;t t', instead of `...g'.
       Instead of creating `conftest.vals' with both ac_e, ac_d,
       and ac_u family, preprocess to strip the trailing spaces, and
       create `conftest.defines' with the ac_d family, and then
       `conftest.undefs' for the ac_e family.
       Break up both `conftest.defines' and `conftest.undefs'.  Insert a
       top label and a global test for `#defines' and `#undef' before.
       Call `conftest.defines' if there are #define in the input.
       Call `conftest.undefs'.

1999-10-31  Akim Demaille  <[email protected]>

       * acgeneral.m4: Prefer `>file' over `> file' etc.
       * acspecific.m4: Likewise.

1999-10-31  Akim Demaille  <[email protected]>

       Rename the family AC_NEED_DECL as AC_CHECK: it is more uniform,
       but keep defining NEED_FOO_DECL when `foo' is not declared.  Files
       not using Autoconf behave better when declarations lacks than when
       they are wrong.  So the unset position should off, hence #if NEEDS
       instead of #if !HAVE (which is triggered when HAVE is not set).

       * acgeneral.m4 (AC_NEED_DECL): Rename as...
       (AC_CHECK_DECL): This.  Make sure the arguments are the usual
       IF-FOUND, IF-NOT-FOUND.
       (AC_NEED_DECLS, AC_CHECK_DECLS): Likewise.
       * autoconf.texi (Generic Declarations): Document the changes
       aforementioned.
       * autoheader.m4 (AH_NEED_DECLS): Rename as
       (AH_CHECK_DECLS): This.
       (AH_HOOKS): Hook AH_CHECK_DECLS on AC_CHECK_DECLS instead of
       _NEED_.

1999-10-31  Akim Demaille  <[email protected]>

       Revamp the handling of the arguments of config.status: instead of
       looping over config_files etc. to recognize the file names, use
       the case which handles the options.
       Suggested by Alexandre Oliva.

       * acgeneral.m4 (ifset): Rename as...
       (ifval): This.  All callers changed.
       (ifset): New macro, which tests if a macro is set to a non empty
       value.

       * acgeneral.m4: Initialize growing lists and strings to empty, to
       ease the tests.
       (AC_CONFIG_HEADER): Quote AC_LIST_HEADERS in the define, to handle
       the case AC_LIST_HEADERS is initialized.

       * acgeneral.m4: (AC_OUTPUT_CONFIG_STATUS): New macro, pulled out
       from...
       (AC_OUTPUT): Instead of using $1, $2 and $3, pass them to the
       official macros (AC_CONFIG_FILES, AC_OUTPUT_COMMANDS).
       Call AC_OUTPUT_CONFIG_STATUS.
       (option handling): Use the case-esac to recognize arguments.
       (AC_OUTPUT_COMMANDS): Fix the missing fi;done.

1999-10-31  Akim Demaille  <[email protected]>

       Add a means to specify commands to be run by config.status.  At
       the difference of AC_OUTPUT_COMMANDS, require that the set of
       commands be named, so that both
               CONFIG_COMMANDS=foo ./config.status
       and
               ./config.status foo
       perform the Right Thing.

       * acgeneral.m4 (AC_CONFIG_UNIQUE): Also check in
       AC_LIST_COMMANDS.
       (AC_CONFIG_FILES): Remove a dead pushdef.

       (AC_OUTPUT_COMMANDS_COMMANDS): New macro, output config commands
       in config.status.
       (AC_OUTPUT): Take AC_LIST_COMMANDS into account.
       (AC_OUTPUT): Call AC_OUTPUT_COMMANDS_COMMANDS.

1999-10-31  Akim Demaille  <[email protected]>

       New macro: AC_CONFIG_FILES which is very much like AC_OUTPUT but
       that one associates commands to run when a config file is created.
       For instance for a shell script `foo', one uses
       AC_CONFIG_FILES(foo, chmod +x foo).

       In addition, check that the same name is never used twice in
       config files, headers, subdirs and links.

       * acgeneral.m4 (m4_append): Don't insert new line between
       elements.
       (m4_list_append): New macro.
       (AC_CONFIG_IF_MEMBER): New macro which tests if a file is member
       of a config list.
       (AC_CONFIG_UNIQUE): New macro which ensures that a config file
       name is not yet used.
       (AC_CONFIG_HEADER, AC_CONFIG_LINKS, AC_CONFIG_SUBDIRS): Use
       AC_CONFIG_UNIQUE.

       * acgeneral.m4 (AC_CONFIG_FILES): New macro.
       (AC_LIST_FILES): New list, which stores arguments of
       AC_CONFIG_LISTS the same as AC_LIST_LINKS stores AC_CONFIG_LINKS
       etc.
       (AC_OUTPUT): No longer rely on $1 to designate the config files:
       register them via AC_CONFIG_FILES.  All uses of $1 replaced by
       uses of AC_LIST_FILES.
       (AC_OUTPUT_FILES): Run the commands associated to the
       CONFIG_FILES.

1999-10-31  Akim Demaille  <[email protected]>

       (C Compiler Characteristics): Document AC_C_PROTOTYPES.

       * testsuite/autoconf.s/defines.exp: Changed `fail' and `pass' in

       templates the AC_DEFINEs. Since we no longer rely on acconfig.h,
       the test is obsolete.
       * acspecific.m4 (AC_PROG_BINSH, AC_PROG_SED): Don't quote the name

1999-10-05  Akim Demaille  <[email protected]>

       When you rely on the `t' flag of sed for the immediately

       Bug triggered if you AC_DEFINE(FOO, "%").
       Additionally, work around a bug in IRIX sed.

       Make the handling of the configuration links (AC_LINK_FILES)
       exactly the same as that of configurations files (AC_OUTPUT_FILES)
       and headers (AC_CONFIG_HEADERS).  As a result, it is sane to run
               ./config.status src/libmy_lib
       or
               CONFIG_LINKS=src/lib_mylib:lib/lib_mylib ./config.status

       * acgeneral.m4 (AC_LINK_FILES): Use AC_FATAL to diagnose bad
       number of argument.
       Obsoleted (but implemented) in favor of AC_CONFIG_LINKS.

       * acgeneral.m4 (AC_CONFIG_LINKS): New macro.  Takes space

       Moving most of the task of creating config.h.in from sh to m4.
       Getting rid of acconfig.h by supply a major new family of macros:
       AH_* which make it possible to insert arbitrary text into
       config.h.in.

       * autoheader.m4: Major rewrite: introduction of a set of macros
       AH_ that produce code into config.h.in.  There are two sets of
       macros: generic macros, or specialized, documented below.  The
       basic idea is that an AC_FOO macro which needs an entry in
       config.h.in should have a sibling AH_FOO which expands into that
       entry.  In a near future, these macros will be moved next to their
       siblings.

       * autoheader.m4 (AH_VERBATIM, AH_DEFINE, AH_DEFINE, AH_NEED_DECLS,
       AH_CHECK_SIZEOF, AH_CHECK_FUNCS, AH_CHECK_HEADERS,
       AH_CHECK_HEADERS, AH_CHECK_LIB, AH_PROG_LEX, AH_FUNC_ALLOCA,
       AH_C_CHAR_UNSIGNED, AH_AIX, AH_F77_WRAPPERS): New macros.

       * autoheader.m4 (End section): Bind AC_ macros to their
       AH_siblings.

       * autoheader.sh: Remove the sections in charge of SYMS, TYPES,
       FUNCS, HEADERS, LIBS and DECLS: autoheader.m4 is now in charge of
       these.

       * autoheader.sh (options): Added -d, --debug, which does not
       remove the temporary files.

       * autoheader.sh: Instead of redirecting stdout to the output
       stream, always output to a temporary file.  This allows to change
       slightly the consistency check: before autoheader would check that
       each non documented AC_DEFINE is templated in an acconfig.  Now it
       just checks whether the template is in the output file.

       * acconfig.h: Completely emptied, the remaining templates
       (_ALL_SOURCE, __CHAR_UNSIGNED__, F77_FUNC, F77_FUNC_,
       HAVE_STRINGIZE, and STACK_DIRECTION) are now either associated to
       their AC_DEFINE, or to one of the new AH_ macros.

       * acgeneral.m4: Reordering of the m4 macros which are not specific
       to Autoconf.

       * acgeneral.m4 (AC_HAVE_LIB): Promoted from obsolete to hasbeen.

       * acgeneral.m4 (AC_TR_CPP): Fixed quoting problem, and missing ^
       in patsubst.
       (AC_TR_SH): Fixed quoting problem.

       functions is preferred since they don't require setgid permissions
       to use them. Fix for PR autoconf/65.

1999-09-29  Akim Demaille  <[email protected]>

       * acconfig.h: Commit the change announced below.

1999-09-29  Akim Demaille  <[email protected]>

       * acspecific.m4 (AC_C_CONST): Changed from
       const charset x;
       to
       const charset x = {0, 0};
       From Jim Meyering.

1999-09-28  Akim Demaille  <[email protected]>

       Start to get rid of acconfig.h.  It is an anachronism.

       * acgeneral.m4 (_AC_SH_QUOTE): Both cases must be evaluated the
       same number of times.

       * acconfig.h (_ALLOCA, CLOSEDIR_VOID, const, CRAY_STACKSEG_END,

       uid_t, UMAX, UMAX4_3, USG, vfork, VOID_CLOSEDIR, WORDS_BIGENDIAN,
       X_DISPLAY_MISSING, YYTEXT_POINTER): Removed their autoheader
       template.  They are now documented with their own AC_DEFINE.

       * acgeneral.m4 (AC_HASBEEN): New macro.  Same as AC_OBSOLETE, but
       dies.

       * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_INT_16_BITS,
       AC_LONG_64_BITS): Promoted from obsolete to hasbeen.

       * autoheader.m4 (AC_DEFINE_UNQUOTED): Define via AC_DEFINE, so
       that we program things only once.
       (AC_DEFINE): Use AC_WRAP and _AC_SH_QUOTE.  It is now safe to have
       backquotes and extra spaces in the third argument, without
       yielding a bad result.

       * autoheader.m4: Instead of a huge `eval', use a temporary file.
       (option handling): Added --debug, to keep the temporary files.
       Fixed a couple of missing quotes.

1999-09-28  Akim Demaille  <[email protected]>

       Make AC_FOREACH be robust to active symbols.

       * acgeneral.m4 (m4_split, m4_join, m4_strip): New macros.

       m4_foreach.
       * acgeneral.m4: Spell checked.
       * autoconf.texi: Likewise.

1999-09-28  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_NEED_DECL): When $4 is given, don't provide
       defaults headers.
       Change the message from `have' to `need'.
       Change the actions for `if-(not-)found' to `if-(not-)needed.
       Remove trailing parentheses.

       * acgeneral.m4 (AC_NEED_DECLS): Change the actions for
       `if-(not-)found' to `if-(not-)needed.

       * autoconf.texi (Generic Declarations): Update.

1999-09-27  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT): Divert AC_OUTPUT_FILE to
       AC_DIVERSION_KILL if there are no CONFIG_FILES.
       (AC_OUTPUT, ac_cs_usage): Output the list of files to instanciate
       only if there are.

1999-09-27  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CHECK_DECL): Renamed as...

       autoconf/19.

1999-09-26  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_WRAP): Rewritten.
       (AC_HELP_STRING): Wrapper of AC_WRAP.
       * acgeneral.m4 (_AC_SH_QUOTE): Rewritten.  Don't try to handle
       both backslashed and non backslashed backquotes in a single
       string: consider that either all the backquotes are quoted, or
       none.

1999-09-26  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_PATH_PROG): Use a single case statement for
       Unix and DOS absolute paths.

       * acgeneral.m4 (AC_CHECK_SIZEOF): Fix a typo.
       Allow a third default argument: extra headers.
       * autoconf.texi (C Compiler Characteristics): Document.

       * acgeneral.m4 (AC_CHECK_TYPE): Convert to the AC_VAR_* family.
       Allow a third optional argument: extra includes.
       * autoconf.texi (Generic Typedefs): Documents.

1999-09-26  Ben Elliston  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT_LINKS): Eliminate gratuitous spaces from
       $ac_sources if this variable is otherwise empty. Fix for PR
       autoconf/30.

1999-09-25  Ben Elliston  <[email protected]>

       * autoconf.texi (AC_FUNC_SETVBUF): Do not mention which systems
       might have their setvbuf() arguments reordered. It's difficult to
       accurately determine and is not essential. Fix for PR autoconf/7.

       * acgeneral.m4 (AC_LINK_FILES): Emit an error if an incorrect
       number of arguments are collected. Fix for PR autoconf/10.

1999-09-25  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT, handling of options): Make it possible
       to specify the files to configure on the command line instead of
       via envvars.  Document it.

1999-09-25  Akim Demaille  <[email protected]>

       * acgeneral.m4: Rename the occurences of the variable `confstat'
       as `ac_cs_root'.  The previous name was breaking the naming
       scheme.

1999-10-24  Akim Demaille  <[email protected]>

       * TODO: Updated.
       Added a section for 2.15 and 3.

1999-09-24  Ben Elliston  <[email protected]>

       * acspecific.m4 (AC_HEADER_STDC): Define ISLOWER and ISUPPER
       macros correctly on EBCDIC systems. Contributed by Kurt D.
       Zeilenga. Fix for PR autoconf/6.

1999-09-24  Jim Blandy  <[email protected]>

       as a fix for PR autoconf/21.

       * install.texi: Replace `can not' with `cannot'.

1999-09-23  Pavel Roskin  <[email protected]>

       Avoid that comments from aclocal.m4 show up in configure when
       using AC_REVISION.

       * acgeneral.m4: New diversion levels AC_DIVERSION_KILL and
       AC_DIVERSION_BINSH introduced. Use AC_DIVERSION_KILL as the
       initial value for AC_DIVERSION_CURRENT.
       (AC_INIT_BINSH): Set AC_DIVERSION_BINSH explicitly
       (AC_REVISION): Likewise.
       (AC_INIT): Set AC_DIVERSION_NOTICE when calling AC_INIT_NOTICE.

1999-09-23  Akim Demaille  <[email protected]>

       * NEWS: Document AC_ARG_VAR.

       * acspecific.m4 (AC_C_LONG_DOUBLE): Avoid a needed execution by
       using a pure compilation test.  Excellent for cross compilation.
       From Kaveh R. Ghazi.

1999-09-22  Akim Demaille  <[email protected]>

       * install.texi: Give more details on envvar handling.
       * acgeneral.m4 (AC_HELP_STRING): Add a third argument to tune the
       width of the first column.
       (AC_INIT_NOTICE): Initialize ac_arg_enable_help, ac_arg_with_help,
       and ac_arg_var_help.
       * acgeneral.m4 (AC_INIT_PARSE_ARGS): Remove the handling of
       --env-var=.  After debate, the solution chosen to specify envvars
       to configure is a` la make: ./configure VAR=VAL.
       (AC_INIT_PARSE_ARGS, --help): Output ac_arg_enable_help,
       ac_arg_with_help, and ac_arg_var_help.
       * acgeneral.m4 (AC_ARG_VAR): New macro, to register and document
       influent envvars.
       * acspecific.m4 (AC_PROG_CC): Document CFLAGS.
       This is mainly to test AC_ARG_VAR.  Var to document are to be
       defined.

1999-09-22  Akim Demaille  <[email protected]>

       * acgeneral.m4 (m4_default): New macro.
       (AC_CHECK_LIB): When ACTION-IF-FOUND is specified, don't perform
       the default action.
       Reported by Pavel.

1999-09-22  Ben Elliston  <[email protected]>

       * config.guess: Clear the CCOPTS environment variable before
       invoking the C compiler on HP-UX. This is necessary to guarantee
       that the test program is compiled correctly. Reported by Dietmar
       P. Schindler.

1999-09-22  Linas Vepstas  <[email protected]>

       * config.guess: Add OS/390 match pattern.
       * config.sub: Add mvs, openedition targets.

       * config.sub: Add fr30 target.

1999-09-21  Ben Elliston  <[email protected]>

       * configure.in: Check if an appropriate version of GNU m4 is
       installed at configure-time rather than at runtime. From Pavel
       Roskin. Fix for PR autoconf/2.
       * configure: Regenerate.

1999-09-21  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_INIT_PARSE_ARGS, --help message): Use quoted
       heredocs to avoid problems with quotes.

1999-09-21  Akim Demaille  <[email protected]>

       * NEWS: Updated.
       * THANKS: Likewise.

       * acgeneral.m4 (AC_CHECK_HEADER): Use AC_VAR_*.
       (AC_CHECK_HEADERS): Adapted.

       * acgeneral.m4 (AC_TR): Remove, it is useless.
       (AC_TR_CPP): Updated version of formerly AC_TR_DEFINE, based on
       the model of AC_TR_SH.
       All callers changed.

       * autoconf.sh (Checking for Bugs): Remove the indirection that
       made the `sort -u' useless.

1999-09-21  Akim Demaille  <[email protected]>

       * autoconf.sh (Last sed cmd): Change also @PND@ to `#', since this
       is also a symbol very hard to quote in m4.

       * acgeneral.m4 (AC_CHECK_LIB): Use AC_VAR_*.

       * acgeneral.m4: Use `m4_BUILTIN' instead of indirection via
       `builtin'.

1999-09-21  Akim Demaille  <[email protected]>

       * autoconf.texi (Particular Structures): Move documentation of
       AC_HEADER_STAT and AC_HEADER_TIME from here...
       (Particular Headers): to here.
       (Declarations): New section.
       (Particular Headers): Move doc of AC_DECL_SYS_SIGLIST from here...
       (Particular Declarations): to here.

1999-09-21  Kaveh R. Ghazi  <[email protected]>

       * acgeneral.m4 (AC_CHECK_FUNC_DECL, AC_CHECK_FUNC_DECLS): New
       macros.

       * autoconf.texi (AC_CHECK_FUNC_DECL, AC_CHECK_FUNC_DECLS):
       Document.

       * autoheader.m4: Add support for AC_CHECK_FUNC_DECLS.

       * autoheader.sh: Likewise.

1999-09-21  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_SHELL_IFELSE): New macro.
       (AC_VAR_IF_SET): Use it.
       (AC_CHECK_FUNC): Likewise.

       * Makefile.in (${srcdir}/configure): Use autoconf.sh to build
       Autoconf's configure.  Before the building was performed running
       m4 at hand, but much was not done (e.g., __oline__,
       @BKL@... expansion)

1999-09-20  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT): Don't remove the CONFIG_HEADERS
       unconditionaly: it breaks the `config.h has not changed' trick.

1999-09-20  Ben Elliston  <[email protected]>

       * autoheader.sh: Bourne shell compatibility fix. From Pavel Roskin.

1999-09-20  Pavel Roskin  <[email protected]>

       * autoheader.sh: Fix the tr invocation.

1999-09-17  Ben Elliston  <[email protected]>

       * config.guess: Detect QNX version 4.

1999-09-17  Erez Zadok  <[email protected]>

       * config.guess: Eliminate the trailing dot if ${UNAME_RELEASE} is
       1.4-<SOMETHING>. Fix for PR autoconf/22.

1999-09-17  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_INIT_PARSE_ARGS): Improve configure's --help.

       * acgeneral.m4 (AC_OUTPUT): Change the root of filenames of
       config.status from $conftest to $confstat.
       The previous patch to make config.status reentrant was wrong,
       because it changed some `conftest' that are used by configure into
       `$conftest', while it was for config.status only.  To avoid
       another confusion like this, all the filenames of config.status
       should be `$confstat*', and those of configure should be
       `conftest*'.
       (AC_OUTPUT): Rename the uses of `ac_file' for the sed fragments as
       `ac_sed_frag'.

       * acgeneral.m4 (AC_OUTPUT): This macro used to open the here
       documents that configure uses to generate config.status, included
       that of the submacros.  Now, it no longer handles the here
       documents for its subroutines (it was far to hard to track).
       (AC_OUTPUT_FILES): Open and close your here documents to
       $CONFIG_STATUS.
       (AC_OUTPUT_HEADER): Likewise.
       (AC_OUTPUT_LINKS): Likewise.

       * acgeneral.m4 (AC_OUTPUT_FILES): Move $ac_vpsub and $extrasub
       from the AC_SUBST substitutions (i.e., that of @SHELL@ etc.) to
       the specific section (that of @srcdir@ etc.).
       Now the ``general substitution'' section is absolutely uniform.

       * acgeneral.m4 (AC_SUBST): Change sed call from `s%@from@%to%g'
       into `s%@from@%to%;t t'.
       (AC_SUBST_FILE): Likewise.
       (AC_OUTPUT_FILES): Optimize the sed scripts by branching if there
       are no `@' on the line. Impressive speed up.

       * Makefile.in (DISTFILES): Add THANKS.

       * THANKS: New file.

1999-09-15  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_CHECK_FILE): Use ifset.
       (AC_CHECK_FUNC): Updated to use AC_VAR_*, and AC_CACHE_CHECK.
       (AC_CHECK_SIZEOF): Likewise.
       (AC_CACHE_CHECK): Use AC_MSG_RESULT_UNQUOTED.
       (AC_MSG_RESULT_UNQUOTED): New macro.

1999-09-15  Alexandre Oliva  <[email protected]>

       Fix for PR autoconf/28.
       * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS): Don't assume LF is \012, use
       `echo` followed by a non-blank, within quotes.
       * autoheader.sh (syms): Likewise.
       * configure: Rebuilt.

1999-09-14  Alexandre Oliva  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS): Don't assume LF is \012,
       use `echo` followed by a non-blank, within quotes.
       * autoheader.sh (syms): Likewise.
       * configure: Rebuilt.
       Reported by Christian Krone.

       * acgeneral.m4 (AC_INCLUDE): New macro.
       * autoconf.texi: Document it.

       * acgeneral.m4 (AC_OUTPUT_SUBDIRS): Save INSTALL in
       ac_given_INSTALL, so that we can adjust relative pathnames for
       sub-configures.

       * acgeneral.m4 (Configuration): Accept --env-VAR=VALUE and
       VAR=value.
       * autoconf.texi, install.texi: Document it.
       * configure: Rebuilt.

1999-09-14  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_HELP_STRING): Rewrite in m4.  Have m4 work, and
       give a break to sh.
       (_AC_FOREACH): Be careful not to evaluate the arguments.  A loop
       over *quoted* macro names should loop over the macro names, not
       upon their expansion.
       (_AC_COMMATIZE): Also swallow end of lines.

       * autoconf.texi (Pretty Help Strings): Updated to reflect the
       changes.

1999-09-13  Akim Demaille  <[email protected]>

       * acgeneral.m4 (ifset): New helpy tiny macro.
       (AC_OUTPUT): Improved --help of config.status.
       (AC_OUTPUT): Remove inconditionaly all the files to be updated.
       (AC_OUTPUT): Use pid to define the temporary file names in order
       to allow parallel builds.

       * autoconf.sh: Substitute also /@BKL@/[/ /@BKR@/]/ /@DLR@/$/ so
       that these characters are more easily accessible from m4 without
       turning changequote juggling into a nightmare.

       * acgeneral.m4 (AC_WRAP): New macro, for word wrapping.

       * autoconf.texi: Update the direntry for more modern Texinfos.
       Add pointer to configure and config.status.
       Remove the dots from the menus: horizontal space is precious.
       (Invoking config.status): More traditional presentation of the options.

1999-09-07  Ben Elliston  <[email protected]>

       * autoreconf.sh: Recognise -v as a synonym for --verbose.

1999-09-07  Gary V. Vaughan  <[email protected]>

       * Makefile.in (INSTALL, standards.info, autoconf.info):  MiKTeX
       for Windows treats all options after the first filename as
       additional filenames, so real options must appear before the first
       filename.

1999-09-07  Steven G. Johnson  <[email protected]>

       * autoconf.texi (LDFLAGS, LIBS): Document that -L linker flags
       should be kept in LDFLAGS and not LIBS.

1999-09-07  Jim Meyering  <[email protected]>

       * acgeneral.m4 (AC_SEARCH_LIBS): Use $ac_lib as the index, not $i.

1999-09-06  Ben Elliston  <[email protected]>

       * acspecific.m4 (AC_FUNC_ALLOCA): Rename cache variable to avoid
       name clashes with AC_CHECK_HEADER(alloca.h).

1999-09-05  Steve Chamberlain  <[email protected]>

       * config.sub: Add support for configuring for picoJava (pj).

1999-09-05  Ben Elliston  <[email protected]>

       * acgeneral.m4 (CONFIG_AUX_DIRS): Try running `shtool install'.
       Contributed by Ralf S. Engelschall.

1999-09-04  Ben Elliston  <[email protected]>

       * config.guess: Use POSIX compliant shell code on DG/UX.
       Suggested by Stephen Gildea.

1999-09-04  Pavel Roskin  <[email protected]>

       * acgeneral.m4 (AC_OUTPUT_FILES): Output comment to not only
       `Makefile', but also `makefile'.

1999-09-04  Jim Blandy  <[email protected]>

       * Makefile.in (install): Don't freak if the M4FROZEN files were
       never generated.  m4 1.1 is supported, but doesn't freeze files.

1999-09-04  Scott Bambrough  <[email protected]>

       * config.guess: Autodetect ArmLinux using 2.9.1.xx linker
       emulation names and using the emulation names from the linker from
       the binutils CVS tree.

       * config.sub: Change manufacturer name for the NetWinder alias
       from Corel to Rebel.

1999-09-04  Jeremy Elson  <[email protected]>

       * autoheader.m4 (AC_CHECK_HEADER): Define.

1999-09-02  Tom Tromey  <[email protected]>

       * autoheader.sh: Allow multiple spaces between #undef and symbol
       name.

1999-09-01  Akim Demaille  <[email protected]>

       * acgeneral.m4 (AC_ACVERSION): Bump to 2.14.1 to differenciate the
       experimental branch from the main trunk.

       * acgeneral.m4 (AC_FOREACH_COMMA): New macro, to perform m4 loops
       on m4 lists (i.e., list='(item_1, item_2, ..., item_n)').
       (AC_FOREACH): New macro, to perform m4 loops on shell lists (i.e.,
       list='item_1 item_2 ... item_n').

       * acgeneral.m4 (AC_DEFUN): Now accept two other optionnal
       parameters: the name of the macro which is specialized here, and
       the name of the first argument.  For instance `AC_CHECK_FNMATCH'
       should be declared as specializing `AC_CHECK_FUNC' for `fnmatch'
       as first argument.

       * acgeneral.m4 (AC_CHECK_FILES): Use AC_FOREACH for looping,
       instead of the shell's loop.

       * acgeneral.m4 (AC_TR): In addition to transliteration, provide a
       means to specify the valid destination alphabet and a default
       character for aliens characters.  This is in order to remove
       characters such as `+:-' etc. that may appear in file names, but
       are not valid for shell variables or #defines.
       (AC_TR_DEFINE): New macro, maps anything to a valid uppercase
       #define rhs.
       (AC_TR_UPCASE_NAME): Replaced by AC_TR_DEFINE.  All callers
       changed.
       (AC_TR_UPCASE_FILE): Likewise.

       * acgeneral.m4 (AC_TR_SH): Don't use the generic AC_TR: there is a
       difficult problem of quoting between m4 and sh.  Use the variable
       $ac_tr_sh to work around this difficulty.
       (AC_VAR_TEST_SET): New macro, which tests if a variable is set.
       (AC_VAR_IF_SET): New `ifelse' macro.

       * autoheader.sh: Take the multiple-include protection back out.
       It's not needed for a file that just #defines stuff, and, as Ken
       Raeburn pointed out in Apr 1994:
       Since you don't make it optional, and you don't give the writer of

       (AC_FUNC_VFORK): Call _exit after perror.

       Don't add "-L" to LDFLAGS if $x_libraries is empty.
       (AC_FUNC_STRFTIME): Check for it in -lintl only if it's not in the
       normal libraries.

       * Test release 2.10.3.

       * acspecific.m4 (AC_AIX, AC_MINIX): Remove warnings about AC_TRY_LINK.
       These macros don't change the linkage options.

       of -O.  Suggested by [email protected] (Fred Fish).

       AC_CONFIG_HEADER a value containing shell variables.  Suggested by

       * acgeneral.m4 (AC_TRY_COMPILE, AC_TRY_LINK): Deal with smart
       compilers that know that an unused function doesn't have to be
       linked in: call the function directly from main().
       (Removing a legacy from when they tried to run the code, I think-djm.)
       From [email protected] (Fred Fish).

       * acspecific.m4 (AC_FUNC_GETLOADAVG): Rename ac_save_LIBS to avoid
       a clash with AC_CHECK_LIB.
       From Jim Meyering.

       AC_FUNC_STRCOLL, AC_FUNC_MEMCMP): Rename cache variables to avoid
       wrong results if someone calls AC_CHECK_FUNC for these functions.

       * autoheader.sh: Don't cmp with config.h.in if it doesn't exist yet.
       Don't frob lines 1-@TOP@ or @BOTTOM@-end of acconfig.h's.
