It was an early bug in Neals code, which made it a compound statement
(Neal was trying to make soemthing that looks like a struct foo cast,
but that makes it a compound statement, and that is not constant, see
the discussion from gcc bug list that was CC'ed here a few weeks ago).

I think it is fixed in CVS by now, but I can not check.  In fact, I am
not here.  You didn't see this email :)

Thanks,
