Do we want to let cpp(1) hide warnings in system headers?
Sigh. It's been a while since I've fixed the "feature" of gcc(1)
that makes it hide warnings in system headers (but visible with
-nostdinc -I/usr/include). I've stumbled upon a problem today,
wondering, why the hell cpp(1) wasn't complaining me about the
redefines, and the answer was: GNU cpp(1) hides warnings in system
headers by default. Rather than hack contrib/gcc sources, it can
be fixed the official way, like this:

Anyone objects to having this in?
