+
+       Add Yacc library, since POSIX requires it.
+       * doc/bison.texinfo (Yacc Library): New node.  Regenerate top menu.
+       * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
+       * lib/main.c, lib/yyerror.c: New files.
+
+       gram_error can be static; it need not be extern.
+       * src/reader.h (gram_error): Remove decl.
+       * src/parse-gram.y (gram_error): Now static.  Add static decl.
+       (print_token_value): Omit parameter names from forward decl,
+       for consistency.

+       * doc/bison.texinfo: Emphasize that yylex and yyerror must
+       be declared before being used.  E.g., one should typically
+       declare them in the prologue.  Use GNU coding style in examples.
+       Put "const" consistently after the type it modifies.  Mention
+       that C99 supports "inline".  Mention that yyerror traditionally
+       returns "int".
+
        %parse-param and %lex-param now take just one argument, the
        declaration; the argument name is deduced from the declaration.
