I disagree. If the next OpenBSD release uses Clang by default, we're not
building QEMU there with the *working default* C compiler anymore.
You're then rather forcing the OpenBSD users then to install an
additional (likely unliked, since GPLv3) GCC package on their systems.
So IMHO, just drop this patch and wait for the next OpenBSD release, and
the problem will be solved automatically. (and the few users who still
use an older release of OpenBSD will likely use the QEMU from their
ports system anyway)
Another possible approach would be to have a configure test
for whatever feature it is that we need in our compiler,
and then run through a list that starts with "cc" and
goes on to try "egcc" etc until it finds one that works.
That way we'll automatically DTRT when OpenBSD upgrades
their "cc" to a working one.
