Emacs regular expressions forked from everyone else long ago. This makes it official and should allow simplification later. etags.c now uses the glibc regex API, falling back on a Gnulib-supplied substitute lib/regex.c if necessary. Emacs proper now uses its own regular expression module. Although this patch may look dauntingly large, most of it was generated automatically by admin/merge-gnulib and contains an exact copy of the glibc regex source, and the by-hand changes do not grow the Emacs source code. * admin/merge-gnulib (GNULIB_MODULES): Add regex. (AVOIDED_MODULES): Add btowc, langinfo, lock, mbrtowc, mbsinit, nl_langinfo, wchar, wcrtomb, wctype-h. * lib-src/Makefile.in (regex-emacs.o): Remove; Gnulib does it now. (etags_deps, etags_libs): Remove regex-emacs.o. * lib-src/etags.c: Go back to including regex.h. (add_regex): Use unsigned char translation array, since glibc regex requires that. * lib/Makefile.in (not_emacs_OBJECTS, for_emacs_OBJECTS): New macros. (libegnu_a_OBJECTS): Use them, to avoid building e-regex.o. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/regcomp.c, lib/regex.c, lib/regex.h, lib/regex_internal.c: * lib/regex_internal.h, lib/regexec.c, m4/builtin-expect.m4: * m4/eealloc.m4, m4/glibc21.m4, m4/mbstate_t.m4, m4/regex.m4: New files, copied from Gnulib. * src/regex-emacs.h, src/conf_post.h: (RE_TRANSLATE_TYPE, RE_TRANSLATE, RE_TRANSLATE_P): Move from src/conf_post.h to src/regex-emacs.h, so that they don’t interfere with compiling lib/regex.c.
