+
+	Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
+	GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
+	lookahead symbol, and which sets yychar in parser actions) and it
+	disagreed with the Bison documentation.  This should fix the bug
+	reported by Andrew Walrond in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
+	
+	* data/yacc.c (YYTRANSLATE): Don't check for negative argument,
+	as the caller now does that.
+	(yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
+	(YYEMPTY): Parenthesize right hand side, since others use it.
+	(yyparse): Don't assume that our generated code is the only code
+	that sets yychar.
+
+2002-12-13  Paul Eggert  <eggert@twinsun.com>
+

+	(MOSTLYCLEANFILES): Add yacc.
+	(yacc): New rule.
+	* doc/bison.texinfo (Invocation, Bison Options): Mention yacc
+	as an alias for bison y.
+
+	* po/LINGUAS: Add da.
+	
+	* src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
+	problem with latest <getopt.h>.
+	(HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
+
+	* doc/fdl.texi: Upgrade to 1.2.
+	* lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h

+
+	Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.
+	* data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
+	locations are requested.
+	(union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
+	locations are requested.
