+ (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.
