+       tests: skip tests of file names that platform does not support.
+       Reported by Michael Raskin at
+       <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00001.html>.
+       * THANKS (Michael Raskin): Add.
+       * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix.  Cygwin used
+       to fail at least for file names containing ":" or "\".

+       yysyntax_error: avoid duplicate lookahead collection.
+       Except when memory reallocation is required, this change
+       eliminates the need to invoke yysyntax_error twice and thus to
+       repeat the collection of lookaheads.  It also prepares for
+       future extensions that will make those repetitions more
+       expensive and that will require additional memory management in
+       yysyntax_error.  Finally, it fixes an obscure bug already
+       exercised in the test suite.
+       * data/yacc.c (yysyntax_error): Add arguments for message
+       buffer variables stored in the parser.  Instead of size, return
+       status similar to yyparse status but indicating success of
+       message creation.  Other than the actual reallocation of the
+       message buffer, import and clean up memory management code
+       from...
+       (yyparse, yypush_parse): ... here.
+       * tests/regression.at (parse.error=verbose overflow): No longer
+       an expected failure.

+
+       yysyntax_error: test memory management more.
+       * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro.
+       * tests/regression.at (parse.error=verbose and
+       YYSTACK_USE_ALLOCA): New test group.
+       (parse.error=verbose overflow): New test group that reveals an
+       obscure bug.  Expected fail for now.

+
+       benchmarks: use %debug consistently among grammars.
+       * etc/bench.pl.in (generate_grammar_triangular): Do not activate
+       %debug by default.  It can affect the timings even if yydebug=0.
+       (generate_grammar_calc): For consistency with other grammars,
+       use YYDEBUG environment variable to set yydebug.
