* lib/Makefile.in (.SUFFIXES):
* lwlib/Makefile.in (.SUFFIXES):
* oldXMenu/Makefile.in (.SUFFIXES):
* src/Makefile.in (.SUFFIXES): Register .c as a default suffix,
for this list is emptied when `-r' is provided to Make.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* configure.ac (AUTODEPEND_PARENTS): New var.
mkdir the dependency directories here, to simplify ‘make’.
Remove dependency files just before outputting Makefiles, so that
they are preserved if ‘configure’ exits early due to some other problem.
* lib/Makefile.in, lwlib/Makefile.in, oldXMenu/Makefile.in:
* src/Makefile.in: Adjust deps strategies to be similar, as follows:
(MKDEPDIR): Remove. All uses removed. This cuts down on the
number of processes spun off by ‘make’.
(clean mostlyclean): Remove $(DEPDIR) contents, not $(DEPDIR) itself.
(distclean): Remove $(DEPDIR) itself.
* lwlib/Makefile.in (all): Move to front, so that depdir includes
do not alter default action.
* lib-src/Makefile.in (tagsfiles): New variable.
(TAGS): Also depend on the source files. Use our own etags program.
* lisp/Makefile.in (ETAGS): Add EXEEXT.
(lisptagsfiles1, lisptagsfiles2, lisptagsfiles3, lisptagsfiles4):
Remove.
(tagsfiles): New, replacing lisptagsfiles1 etc.
Remove irrelevant source files here rather than in the TAGS rule.
(${ETAGS}): New rule.
(TAGS): Also depend on the etags executable.
* lwlib/Makefile.in (EXEEXT): New, set by configure.
(ETAGS): Add EXEEXT.
(${ETAGS}): New rule.
(ctagsfiles): Use "wildcard".
(TAGS): Also depend on the etags executable.
* nt/Makefile.in (ETAGS, tagsfiles): New variables.
(${ETAGS}): New rule.
(TAGS): Fix dependencies.
* oldXMenu/Makefile.in (EXEEXT): New, set by configure.
(ETAGS): New variable, replacing $TAGS. Use our own etags program.
Remove "-t" argument.
(${ETAGS}): New rule.
(tagsfiles): New variable.
(TAGS): New rule, with proper dependencies.
* src/Makefile.in (ETAGS): Add EXEEXT. Add a build rule.
(ctagsfiles1, ctagsfiles2): Use "wildcard".
(ctagsfiles3): Remove.
(TAGS): Depend on etags.
(../lisp/TAGS, $(lwlibdir)/TAGS): Let the rules in the relevant
directories decide if updates are needed.
* configure.ac (DEPDIR, MKDEPDIR, deps_frag, lwlib_deps_frag)
(oldxmenu_deps_frag, lisp_frag): Remove output variables/files.
(AUTO_DEPEND): New output variable.
* lwlib/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(lwlib_deps_frag): Replace by conditional include.
* lwlib/autodeps.mk: Remove file.
* oldXMenu/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(oldxmenu_deps_frag): Replace by conditional include.
* oldXMenu/autodeps.mk: Remove file.
* src/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(lisp_frag): Replace by an include.
(deps_frag): Replace by conditional include.
* src/autodeps.mk: Remove file.
* 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.
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...

when including system files with GCC.

* 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.

@c_switch_system@, @c_switch_machine@.
