GPC -- Gnu Pascal Compiler
                       ==========================

       All parts of this compiler are copyrighted (C) by the Free
       Software Foundation, Inc (FSF).

       The Pascal run time system is donated to FSF to be distributed
       according to the FSF Library Copyright.

       See files COPYING and COPYING.LIB in corresponding directories
       to see the permissions you have and what you don't have when
       using this software.

       Everything is done with quite minimal changes to the GCC code,
       so don't be too excited if you get error messages telling that
       ANSI C denies something, or that your STRUCT definition is
       broken, and what not. (Please send me sample code that
       triggers such messages so I can fix it).

       I did it this way, as I wanted it to be easier to upgrade to
       new releases of GCC, and of course since it was a lot easier
       for me to modify code than to write it from scratch.

       There are some new files not present in the GCC; gpc-parser.y
       which is the bison parser for the language, gpc-lex.c that has
       the lexical analyzer stuff, gpc-defs.h which has definitions
       used in various places, and gpc-util.c which includes the glue
       to convert Pascal's way of thinking to the way the original
       C-oriented c-*.c files think, and most of the new routines.

       All changes are flagged with #ifdef GPC (except those that are
       already merged with the mainline GCC code).  Some language
       independent files have also been modified, but most of the
       changes are quite minimal or if not, new code has been added
       to handle pascal. All in all, the GCC compiler is quite well
       designed to support at least these kind of languages.

       GPC tries to be (for now) a Level 0 ISO 7185 compatible Pascal
       processor. There are two levels in the Pascal standard; level
       0 processors are not required to understand conformant arrays
       (this is the only difference). The conformant arrays are
       partially implemented in this version, but more likely they
       crash the compiler than work at this time.

       I don't have the ANSI standard, so I can't make
       the comparision between ISO & ANSI, and it not the most
       important thing now, anyway.  After everything else works,
       it should be *easy* to implement the ANSI standard
       modifications to the compiler. I think.

       GPC also imlements a large subset of the ISO/IEC 10206
       international standard of the Extended Pascal language.
       (See GPC.GUIDE for more info).

       See the file PROBLEMS to find out the major problems
       of the GPC version in this directory.

       The file NEW-PVS-LIST contains the current results of running
       the Pascal Validation Suite conformance tests (about 199
       tests), one line (word) to tell why the test failed. PASSed
       tests are not mentioned.  PVS tests also contain QUALITY
       tests, errorhandling tests, implementation dependent tests,
       but they will be checked later.

       ChangeLog contains a partial edit history.

                       Yours,
