* modules/regex (Files): Add lib/regex_internal.c, lib/regex_internal.h, lib/regexec.c, lib/regcomp.c, m4/codeset.m4. (Depends-on): Add extensions. (Makefile.am): Remove lib_SOURCES; now done by m4 code. * config/srclist.txt: Add regcomp.c, regex.c, regex.h, regex_internal.c, regexec.c. Add regex_internal.h too, but as a comment, since the libc version is currently broken in gnulib mode. * lib/regex.c, lib/regex.h: Sync from libc. * lib/regcomp.c, lib/regexec_internal.c, lib/regex_internal.h, lib/regexec.c: New files, synced from libc, except that regex_internal.h currently has a small porting fix. * m4/regex.m4: Adjust to new libc regex implementation. (gl_INCLUDED_REGEX): Add AC_LIBSOURCES for all the .c and .h parts of (the new) regex. Quote the m4 stuff better. Check for RE_ICASE bug of old gnulib. Check for REG_STARTEND of recent libc. Rename local variables from jm_* to gl_*. Quote operand of "test -f". Say "recent enough" version of libc, not "version 2". (gl_PREREQ_REGEX): Remove AC_FUNC_ALLOCA, since alloca is a prerequisite module. Remove AC_HEADER_STDC; no longer needed. Check for locale.h, isblank, mbrtowc, wcrtomb, wcscoll. Remove check for btowc, isascii. Require AM_LANGINFO_CODESET.
