 2006-01-03  Paul Eggert  <eggert@cs.ucla.edu>
 
+	* doc/bison.texinfo (Bison Options): Say more accurately what
+	--yacc does.
+	* src/parse-gram.y (rules_or_grammar_declaration): Don't complain
+	about declarations in the grammar when in Yacc mode, as POSIX does
+	not require a diagnostic when the grammar uses extensions.
+
+	* src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
+
+	Warn about dubious constructions like "%token T T".
+	Reported by twlevo.
+	* src/symtab.h (struct symbol.declared): New member.
+	* src/symtab.c (symbol_new): Initialize it to false.
+	(symbol_class_set): New arg DECLARING, specifying whether
+	this is a declaration that we want to warn about, if there
+	is more than one of them.  All uses changed.
+
+	* data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
+	Allow multiple %union directives, whose contents concatenate.
+	* src/parse-gram.y (grammar_declaration): Likewise.
+	Use muscle_code_grow, so that we don't need stype_line any more.
+	All uses changed.
+
+	* src/muscle_tab.c (muscle_grow): Fix comment.
+
 	* ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
 	* data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
 	Update copyright year to 2006.
