Huh?  Prototypes are their own scope.  The names in a prototype are
not going to affect anyone's namespace.

How long will it be before we start not caring about pre-ANSI C?  I mean,
at this point, do there exist platforms that we could meaningfully support
without it?  AFAIK, gcc runs on everything we're likely to care about
anyway.
