+	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.

+	* src/symtab.c (symbol_pack): Here because every symbol's number
