OSX 10.6's clang (whatever that was) is probably the most
likely I'd guess.

If we did want to require a newer compiler there are a
bunch of QEMU_GNUC_PREREQ(3,4) calls that could be
obsoleted. But we should probably do that as a separate
thread to get some consensus on what the minimum version
should be, and put a helpful check in configure and
a line in the release notes and so on...
