* src/Makefile.in (abs_srcdir): New, set by configure.
(maintainer-clean): Remove pointless echo. That should be in the
top-level Makefile, if anywhere. Delete TAGS-LISP.
(extraclean): No s/ and m/ directories for some time.
(TAGS): Remove no-longer-defined S_FILE.
Pass absolute filenames to etags once more.
(TAGS-LISP, $(lwlibdir)/TAGS): Correctly pass ETAGS to sub-makes.
($(lwlibdir)/TAGS): Remove useless subshell, check cd return value.
* lisp/Makefile.in (lisptagsfiles1, lisptagsfiles2, lisptagsfiles3)
(lisptagsfiles4): Use absolute filenames again.
(TAGS, TAGS-LISP): Not everything needs to run in one line.
Remove all *loaddefs files, not just the first. Remove esh-groups.
(maintainer-clean): Delete TAGS, TAGS-LISP.
* lwlib/Makefile.in (abs_srcdir): New, set by configure.
(ETAGS, ctagsfiles): New variables.
(TAGS): Use ETAGS, ctagsfiles. Use absolute filenames again.
* Makefile.in (lib): Depend on am--refresh, to avoid a race.
(src): Remove duplicate dependency on FRC.
Invoke just one submake, not two. Avoid the need for 'pwd'.
* lwlib/Makefile.in (all): Put this first. Don't use double-colon
rules, as they are not portable according to POSIX. Mark as phony.
* oldXMenu/Makefile.in (all, tags): Don't use double-colon rules, as they
are not portable according to POSIX. Mark as phony.
* src/Makefile.in (config.status): Don't use double-colon rules, as
they are not portable according to POSIX. Fix shell typo with `;
I guess this rule has never been tested?
(VCSWITNESS): New macro, to override any environment var.
strcasecmp and strncasecmp.
* lib-src/etags.c (etags_strcasecmp, etags_strncasecmp): Define to
library functions strcasecmp and strncasecmp if available.
* lwlib/lwlib.c (my_strcasecmp): Rename to lwlib_strcasecmp, which
may be defined to library function strcasecmp if available.
* src/dispextern.c (xstrcasecmp): Define to library function
strcasecmp if available.
* src/xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
* etc/PROBLEMS: Remove obsolete '#define static' cruft.
* lwlib/xlwmenu.c [emacs]: Include "bitmaps/gray.xbm".
(gray_bitmap_width, gray_bitmap_height, gray_bitmap_bits) [!emacs]:
Remove; all uses replaced with definiens.
* src/s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
This #undef was "temporary" in 2000; it is no longer needed
now that '#define static' has gone away.
* src/xfns.c, src/xterm.h (gray_bitmap_width, gray_bitmap_height)
(gray_bitmap_bits): Remove; no longer needed.
All uses replaced with definiens.
* src/xterm.c: Include "bitmaps/gray.xbm".
This is the only thing left that uses it.
* configure.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
* src/Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
* lwlib/Makefile.in (C_SWITCH_X_SYSTEM): Remove.
(ALL_CFLAGS): Remove C_SWITCH_X_SYSTEM.
* oldXMenu/Makefile.in (C_SWITCH_X_SYSTEM): Remove.
(ALL_CFLAGS): Remove C_SWITCH_X_SYSTEM.
* msdos/sedlibmk.inp, msdos/sed1v2.inp:
GNUSTEP_CFLAGS replaces C_SWITCH_X_SYSTEM.
I have been using this change for many months in my private copy
of Emacs, and have used it to find several bugs. It's mature
enough to publish now.
* Makefile.in (GNULIB_MODULES): Add warnings, manywarnings.
* configure.in: Support --enable-gcc-warnings, in the style of
other GNU packages such as coreutils.
(C_WARNINGS_SWITCH): Remove, replacing with...
(WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable.
(PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I,
when including system files with GCC.
* etc/NEWS: Mention --enable-gcc-warnings.
* lib/Makefile.am (AM_CFLAGS): New macro.
* m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib.
* lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(BASE_CFLAGS): Use new macros rather than old.
* lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
* src/regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
-Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
-Wunused-result, -Wunused-variable. This should go away once
the Emacs and Gnulib regex code is merged.
(xmalloc, xrealloc): Now static.
