Track CVS Autoconf on AC_USE_SYSTEM_EXTENSIONS. * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Update to CVS Autoconf definition. * modules/euidaccess (Depends-on): Add extensions, for AC_USE_SYSTEM_EXTENSIONS with autoconf <= 2.59. * modules/fnmatch (Depends-on): Likewise. * modules/getaddrinfo (Depends-on): Likewise. * modules/getdelim (Depends-on): Likewise. * modules/getline (Depends-on): Likewise. * modules/getsubopt (Depends-on): Likewise. * modules/gettext (Depends-on): Likewise. * modules/group-member (Depends-on): Likewise. * modules/mbchar (Depends-on): Likewise. * modules/memmem (Depends-on): Likewise. * modules/mempcpy (Depends-on): Likewise. * modules/memrchr (Depends-on): Likewise. * modules/pagealign_alloc (Depends-on): Likewise. * modules/readutmp (Depends-on): Likewise. * modules/stpcpy (Depends-on): Likewise. * modules/stpncpy (Depends-on): Likewise. * modules/strchrnul (Depends-on): Likewise. * modules/strndup (Depends-on): Likewise. * modules/strsep (Depends-on): Likewise. * modules/strverscmp (Depends-on): Likewise. * modules/vasprintf (Depends-on): Likewise. * modules/wcwidth (Depends-on): Likewise. * m4/euidaccess.m4 (gl_FUNC_EUIDACCESS): AC_GNU_SOURCE will be obsolete in Autoconf 2.62; use AC_USE_SYSTEM_EXTENSIONS instead. * m4/fnmatch.m4 (gl_FUNC_FNMATCH_GNU): Likewise. * m4/getaddrinfo.m4 (gl_PREREQ_GETADDR_INFO): Likewise. * m4/getdelim.m4 (gl_FUNC_GETDELIM): Likewise. * m4/getline.m4 (gl_FUNC_GETLINE): Likewise. * m4/getsubopt.m4 (gl_FUNC_GETSUBOPT): Likewise. * m4/glob.m4 (gl_PREREQ_GLOB): Likewise. * m4/group-member.m4 (gl_FUNC_GROUP_MEMBER): Likewise. * m4/mbchar.m4 (gl_MBCHAR): Likewise. * m4/memmem.m4 (gl_FUNC_MEMMEM): Likewise. * m4/mempcpy.m4 (gl_FUNC_MEMPCPY): Likewise. * m4/memrchr.m4 (gl_FUNC_MEMRCHR): Likewise. * m4/mmap-anon.m4 (gl_FUNC_MMAP_ANON): Likewise. * m4/pagealign_alloc.m4 (gl_PAGEALIGN_ALLOC): Likewise. * m4/readutmp.m4 (gl_READUTMP): Likewise. * m4/regex.m4 (gl_PREREQ_REGEX): Likewise. * m4/stpcpy.m4 (gl_FUNC_STPCPY): Likewise. * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Likewise. * m4/strchrnul.m4 (gl_FUNC_STRCHRNUL): Likewise. * m4/strndup.m4 (gl_FUNC_STRNDUP): Likewise. * m4/strnlen.m4 (gl_FUNC_STRNLEN): Likewise. * m4/strsep.m4 (gl_FUNC_STRSEP): Likewise. * m4/strverscmp.m4 (gl_FUNC_STRVERSCMP): Likewise. * m4/vasprintf.m4 (gl_PREREQ_VASPRINTF_H): Likewise. * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Likewise. * m4/lock.m4 (gl_LOCK_EARLY_BODY): Likewise, but provide fallback, so that lock.m4 can be used in gettext without extensions module.
