+ _MSC_VER. Problem reported by Cenzato Marco.
+ (b4_c_function_def): Use it.
+ * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
+ b4_c_modern.
+ (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
+ than rolling our own.

+ * src/reader.c (grammar_midrule_action): If $$ is set in a
+ mid-rule, move the `used' bit to its lhs.
+ * tests/input.at (Unused values): New.
+ * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
+
+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.
