To: xemacs-patches@xemacs.org
PROBLEMS: Include nt/PROBLEMS and update. Add note about incremental
linking badness.
cmdloop.el, custom.el, dumped-lisp.el, files.el, keydefs.el, keymap.el, lisp-mode.el, make-docfile.el, replace.el, simple.el, subr.el, view-less.el, wid-edit.el: Lots of syncing with FSF 21.2.
Use if-fboundp in wid-edit.el.
New file newcomment.el from FSF.
internals/internals.texi: Fix typo.
(Build-Time Dependencies): New node.
PROBLEMS: Delete.
config.inc.samp, xemacs.mak: Eliminate HAVE_VC6, use SUPPORT_EDIT_AND_CONTINUE in its place.
No incremental linking unless SUPPORT_EDIT_AND_CONTINUE, since it
can cause nasty crashes in pdump. Put warnings about this in
config.inc.samp. Report the full compile flags used for src
and lib-src in the Installation output.
alloc.c, lisp.h, ralloc.c, regex.c: Use ALLOCA() in regex.c to avoid excessive stack allocation.
Also fix subtle problem with REL_ALLOC() -- any call to malloc()
(direct or indirect) may relocate rel-alloced data, causing
buffer text to shift. After any such call, regex must update
all its pointers to such data. Add a system, when
ERROR_CHECK_MALLOC, whereby regex.c indicates all the places
it is prepared to handle malloc()/realloc()/free(), and any
calls anywhere in XEmacs outside of this will trigger an abort.
alloc.c, dialog-msw.c, eval.c, event-stream.c, general-slots.h, insdel.c, lisp.h, menubar-msw.c, menubar-x.c: Change *run_hook*_trapping_problems to take a warning class, not
a string. Factor out code to issue warnings, add flag to
call_trapping_problems() to postpone warning issue, and make
*run_hook*_trapping_problems issue their own warnings tailored
to the hook, postponed in the case of safe_run_hook_trapping_problems()
so that the appropriate message can be issued about resetting to
nil only when not `quit'. Make record_unwind_protect_restoring_int()
non-static.
dumper.c: Issue notes about incremental linking problems under Windows.
fileio.c: Mule-ize encrypt/decrypt-string code.
text.h: Spacing changes.
