* modules/glob (Files): Add glob-libc.h. * lib/glob-libc.h: Renamed from glob_.h. The new version is taken from libc's glob.h, except with '#ifdef __GLOB_GNULIB' protecting things that should be done only in gnulib contexts. * lib/glob_.h: New file, containing only the glob things needed for gnulib. (GLOB_PREFIX): Remove. All uses changed to look for __GLOB_GNULIB. (__GLOB_CONCAT, __GLOB_XCONCAT, __GLOB_ID): Remove; no longer needed. (glob, globfree, glob_pattern_p): Now defined simply in terms of rpl_glob, rpl_globfree, rpl_glob_pattern_p. (__GLOB_GNULIB): New macro, to keep the glob.h changes clearer and to respect the namespace rules better. * m4/glob.m4 (gl_GLOB_SUBSTITUTE): AC_LIBSOURCES for glob.c, glob_.h, glob-libc.h. (gl_PREREQ_GLOB): Remove _SYS_CDEFS_H hack; no longer needed.
