+       Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
+       2.61.  Reported by Juan Manuel Guerrero at
+       <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
+       * tests/output.at ("Output file name: ("): Comment out test case for
+       now.
+       ("Output file name: )"): Likewise.

+
+       * GNUmakefile: Update git-version-gen invocation so make dist
+       succeeds.

+
+       Update to the current gnulib CVS repository, and fix trigraph handling
+       in Bison.
+       * bootstrap: Update gnulib CVS repository URL.
+       (symlink_to_dir): Encapsulate the code that guarantees the destination
+       directory exists into...
+       (check_dst_dir): ... this new function, and...
+       (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
+       fail when copying files into lib/uniwidth/.
+       * src/output.c (prepare_symbols): When writing yytname muscles, where
+       symbol names will be encoded in C-string literals, tell quotearg to
+       escape trigraphs.  This used to be the default in gnulib.
+       * tests/regression.at (Token definitions): Because of the change in
+       gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
+       escapes trigraphs in symbol names.  Thus, yytname no longer has
+       trigraphs unnecessarily doubly escaped.  Update test case output.
+       Extend test case to be sure Bison's own error messages will no longer
+       have trigraphs in symbol names unnecessarily escaped once.
