Something like the attached patch? I don't know whether this would work for clang too -- cc'ing Tim who will know or can try it out. I wouldn't backport this one to 4.1, but my first patch was a cleanup plus BSD-specific changes, so a variant on that would be suitable for 4.0/4.1, with (if it works) this new one in unstable. -- Keir
