Not sure what you have in mind here -- Michael's change to his
patch doesn't add separate code for old glib versions, it just
switches to a different API so the same code works on all versions.

I would have been willing to bump the dependency at this point
if it was hard to work around this one, but since we already
have a patch I'd rather use that and defer the dependency
bump til after 2.3.

Incidentally we do at least compile test this, or we wouldn't be
having this conversation. 2.12 can't compile the 'make check'
tests, though, so it is only a compile test... Still in general
I don't expect much of QEMU to be all that dependent on the
underlying OS, if you ignore the KVM parts. About the only
thing with a bad case of API churn is glib, everything else
(libc, X11, SDL, etc) is pretty stable.
