-       Use gnulib ftoastr module.
+       Use gnulib's mktime module.
+       * Makefile.in (GNULIB_MODULES): Add mktime.
+       * configure.in: Remove code no longer needed, as gnulib now does it.
+       (AC_CHECK_FUNCS): Remove mktime.
+       (AC_FUNC_MKTIME, BROKEN_MKTIME): Remove.
+       (__restrict): Remove, as this now gets in the way of the C99
+       support for 'restrict' pulled in by the gnulib mktime module.
+       Code should now use 'restrict' and not '__restrict".
+       (mktime): Remove.
+       * make-dist: Put gnulib-generated files arg-nonnull.h, c++defs.h,
+       and warn-on-use.h into the distribution.
+       
+       Use gnulib's ftoastr module.
        * Makefile.in (GNULIB_MODULES): Add ftoastr.  Remove dummy.
