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.
