Looking closer at the code, it looks like gcc is just being dumb about
the context. The overhead of using -Wcast-qual and most of the others
probably isn't worth it. The one that is probably worth having for Xen,
if only because doing arithmetic on void pointers seems like blatantly
bad form, is -Wpointer-arith.
