(I have no stake in this, just took an interest in it for some reason.)

I agree working it around is preferable, if we can find a deterministic
way to do that. I'm afraid it will require someone to look into, and
understand, the internal AST representation of gcc (with -fdump-tree-*),
and then perturb it through the QEMU source sufficiently.

Also, how about filing that backport bug for Debian? If they backport
the gcc fix, then the issue is solved -- people can be expected to
update their Debian systems fully, before they do any heavy-lifting with
them (like building QEMU).
