This is precisely part of the problem with -Werror. You've now caused
some configure checks to fail that, presumably, were passing before.
Are they worth making warning-free? Some of the warnings may be in
headers we don't control. What do we do then?

So a broken config leads to a broken compile? I guess I'm not seeing
the severity of that.
