Log message:
        If the user does not define YYSTYPE as a macro, Bison now declares it
        using typedef instead of defining it as a macro.  POSIX requires this.
        For consistency, YYLTYPE is also declared instead of defined.
        
        %union directives can now have a tag before the `{', e.g., the
        directive `%union foo {...}' now generates the C code
        `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
        The default union tag is `YYSTYPE', for compatibility with Solaris 9
        Yacc.  For consistency, YYLTYPE's struct tag is now `YYLTYPE'
        instead of `yyltype'.
        
        `yystype' and `yyltype' are now obsolescent macros instead of being
        typedefs or tags; they are no longer documented and will be
        withdrawn in a future release.
