Thanks.  No doubt that will work.

Yes, and they've got a perfect right to not define __STDC__ when you
are using 'cc', since 'cc' is not standarized.  However, we want Bison
to work well even when 'cc' is used.

I guess that the current fixes will do that, since they remove the
stray ';'.  However it is frustrating that Bison generates a parser
that compiles with prototypes disabled, even though the compiler
presumably supports prototypes well.  If you can suggest a better
approach (maybe 'cc' supports another predefined macro?) I'm all ears.
