The Qemu code generation depends (at least for now) heavily on GCC3 and
its particular behaviour. As long as this is the case I don't see the
point of replacing convenient GNU C extensions.

(Once you manage to get Qemu to work with a different compiler the case
for removing GNU C features will be stronger.)
