2007-01-24 Bruno Haible <bruno@clisp.org> Don't AC_REQUIRE autoconf macros that invoke AC_LIBOBJ. See <http://lists.gnu.org/archive/html/bug-gnulib/2006-10/msg00279.html>. * m4/argp.m4 (gl_ARGP): Invoke, don't require, gl_GETOPT_SUBSTITUTE. * m4/fts.m4 (gl_FUNC_FTS, gl_FUNC_FTS_LGPL): Invoke, don't require, gl_FUNC_FTS_CORE. (gl_FUNC_FTS_CORE): Invoke, don't require, gl_FUNC_OPENAT. * m4/lstat.m4 (gl_FUNC_LSTAT): Invoke, don't require, AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK. * m4/memcmp.m4 (gl_FUNC_MEMCMP): Invoke, don't require, AC_FUNC_MEMCMP. * m4/mktime.m4 (gl_FUNC_MKTIME): Invoke, don't require, AC_FUNC_MKTIME. * m4/openat.m4 (gl_FUNC_OPENAT): Invoke, don't require, gl_FUNC_FCHOWNAT. * m4/strftime.m4 (gl_FUNC_GNU_STRFTIME): Invoke, don't require, gl_FUNC_STRFTIME. * m4/strtod.m4 (gl_FUNC_STRTOD): Invoke, don't require, AC_FUNC_STRTOD.
