+       * data/c.m4 (b4_c_modern): New macro, with a new provision for

+       (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.

+       * 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.
