A patchkit is provided for patching up from a pure 20.3 XEmacs source tree
to 20.4. You must have a fairly recent version of patch (ie GNU patch 2.1
or later) that understands unified diff format. Also, if your version of
patch doesn't handle missing files very well (like some versions of GNU
patch 2.x) and you haven't installed the *20.3* XEmacs/Mule sources, you will
wish to do so before applying the patch.
Uncompress the patch kit and cd to the toplevel source directory of
your XEmacs 20.3 sources. Install the 20.3 XEmacs/Mule sources if you
are at all unsure about your patch program.
Execute the patch kit with /bin/sh. There should be no errors or
rejection files (.rej).
Rerun configure with `./config.status --recheck' if you haven't cleaned out
the source tree with `make distclean', otherwise build from scratch as usual.
Note that this version of XEmacs will rebuild everything by default from
a standard `make' command.
Note also that when building the info documentation, it is best to have the
latest version of makeinfo (1.68) from GNU texinfo 3.11.
Report any problems to the comp.emacs.xemacs newsgroup and Good Luck!
