(SUBDIR_MAKEFILES): Update for new doc/ directory layout.
(man/Makefile, lispref/Makefile, lispintro/Makefile): Rename and
update these targets for new doc/ directory layout.
(doc/misc/Makefile): New target.
(install-arch-indep): Use mansrcdir for new location of manpages.
(mostlyclean, clean, distclean, maintainer-clean, unlock)
(relock, info, dvi): Update targets for new doc/ directory layout.
(install-arch-indep, uninstall): Use $(INFO_FILES) to specify files to be
installed/uninstalled.
(uninstall): Invoke "$(INSTALL_INFO) --remove" to remove references to Info
files installed by Emacs.
* Makefile.in (AUTOCONF_INPUTS): New macro.
($(srcdir)/configure, $(srcdir)/src/stamp-h.in): Depend on it,
so that these files also depend on m4/getopt.m4.
* configure.in: Configure getopt by including m4/getopt.m4,
and configuring a getopt replacement if necessary.
* make-dist: Add m4 subdirectory. Unlink lib-src/getopt.h.
* m4/getopt.m4: New file.
* lib-src/Makefile.in (mostlyclean): Remove getopt.h, getopt.h-t.
(GETOPT_H): New macro, from gnulib.
(getopt.h): New rule, from gnulib.
(GETOPTOBJS): Now autoconfigured.
(GETOPTDEPS): getopt.h is now autoconfigured.
(getopt.o, getopt1.o): Depend on $(GETOPT_H), not ${srcdir}/getopt.h.
(getopt.o): Depend on ${srcdir}/gettext.h.
(movemail.o): Depend on $(GETOPT_H).
* lib-src/getopt.c, lib-src/getopt1.c: Sync from gnulib.
* lib-src/getopt_.h, lib-src/getopt_int.h, lib-src/gettext.h:
New files, from gnulib.
* lib-src/getopt.h: Removed (now is getopt_.h).
* nt/inc/gettext.h: Remove; no longer needed now that
lib-src/gettext.h exists.
* src/s/cygwin.h (C_SWITCH_SYSTEM): Remove, since gettext.h is
now part of lib-src.
Tweak arch tagging to make build/install-in-place less annoying
Previously, autoconf-created Makefiles and the like would contain
duplicate taglines (unfortunately, autoconf doesn't seem to have a
`strip in generated file' comment mechanism) leading to conflicts, and
installing in place would create unknown directories and copies of
source directories (leading to conflicts with the source directories).
This changeset makes all autoconf-processed files use explicit id-tags
and adds .arch-inventory entries to ignore installation directories.
