+	Use gnulib's getopt-gnu module.
+	* Makefile.in (GNULIB_MODULES): Add getopt-gnu.
+	(AUTOCONF_INPUTS): Remove getopt.m4; aclocal.m4 is a good-enough
+	representative of the dependencies.
+	* configure.in: Do not configure getopt, as gnulib does that now.
+	* make-dist: Do not worry about lib-src/getopt.h, as gnulib handles
+	getopt now, in lib.
+	
 	Regenerate.
 	* arg-nonnull.h, c++defs.h, lib/mktime-internal.h, lib/mktime.c:
 	* lib/stddef.in.h, lib/time.h, lib/time.in.h, lib/time_r.c:
