* 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 $(DEPDIR) itself.
* lwlib/Makefile.in (all): Move to front, so that depdir includes
do not alter default action.
Emacs now assumes GNU Make, so @SET_MAKE@ is no longer needed.
* Makefile.in, lwlib/Makefile.in, nextstep/Makefile.in:
* src/Makefile.in: Remove @SET_MAKE@.
* lib-src/Makefile.in (tagsfiles): New variable.
(TAGS): Also depend on the source files. Use our own etags program.
* lisp/Makefile.in (ETAGS): Add EXEEXT.
(lisptagsfiles1, lisptagsfiles2, lisptagsfiles3, lisptagsfiles4):
Remove.
(tagsfiles): New, replacing lisptagsfiles1 etc.
Remove irrelevant source files here rather than in the TAGS rule.
(${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.

(AUTO_DEPEND): New output variable.

(deps_frag): Replace by conditional include.
* src/autodeps.mk: Remove file.
* Makefile.in: Use `make -C' rather than `cd && make' throughout.
* lib-src/Makefile.in (../lib/libgnu.a): Use `make -C' rather than `cd && make'.
* lisp/Makefile.in (leim, semantic): Use `make -C' rather than `cd && make'.
* lwlib/Makefile.in ($(globals_h)): Use `make -C' rather than `cd && make'.
* src/Makefile.in: Use `make -C' rather than `cd && make' throughout.
* 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.

(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.
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.

GNUSTEP_CFLAGS replaces C_SWITCH_X_SYSTEM.

of Emacs, and have used it to find several bugs. It's mature
enough to publish now.

other GNU packages such as coreutils.

-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.
