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withdrawn in a future release.
Fix copyright notice.
