I can't get terribly excited about that. The behavior is perfectly well
defined, and has been clearly specified since K&R C, so making it an
error seems well outside the charter of any compilation environment.
As for -Wundef, it seems rather impractical to turn that on anyway given
that it produces numerous other warnings --- a quick check in HEAD shows

We could get rid of some of these but the YY ones are generated by
flex and would probably be difficult to prevent.
Personally what I'd like is to see that chunk of code go away from
c.h altogether --- it ought to live in port/win32.h --- which would
alleviate your concern too. But it would take a bit of refactoring of
win32.h.
