Greetings all.
I am attempting to port QEMU to Plan 9 for the Google Summer of Code.
A big chunk (in terms of diff line count) of the work that has been
done on this before was to convert all the lines of the form
case A ... B:
to be individual case arms as required by Plan 9's C compiler. There
are currently 200 lines in the code base that use this GNU C
extension, which limits the portability of QEMU to platforms with GCC
or a C compiler supporting this particular GNUism. Would a
bulk-conversion patch be accepted?
Thanks much.

qemu already required other gcc extensions for dyngen to work, so IMHO there's
no point removing the other extensions until you remove that.

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.)
