+	Fix bug with non-%union parsers that have printers or destructors,
+	which led to a Bison core dump.  Reported by Peter Fales in
+	<http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
+	
+	* data/c.m4 (b4_symbol_actions): Don't assume %union was used.
+	* data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
+	not to our own type.
+	* src/output.c (symbol_destructors_output, symbol_printers_output):
+	Don't assume %union.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
+	AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
+	UNION-FLAG.  All callers changed.
+	(_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
+	Use type char, not unsigned int, when declaring an array of char;
+	this lets us remove a cast.
+	(Printers and Destructors): Add non-%union test cases.
