+       Obsolete gt_CHECK_DECL in favor of AC_CHECK_DECLS.
+       Now that macros installed by 'gettextize' require Autoconf 2.60,
+       gt_CHECK_DECL can be safely replaced with AC_CHECK_DECLS.
+       * intl.m4 (gt_CHECK_DECL): Remove.
+       (AM_INTL_SUBDIR): Use AC_CHECK_DECLS instead of gt_CHECK_DECL.
+       (gt_INTL_SUBDIR_CORE): Likewise.

        * fcntl-o.m4: Update copyright year.
