Just leave it as it for Bruce to decide.

Not fully right either: there is no <i386/setjmp.h> in 10.8+ ;-)

True: the Solaris fix missed this, probably because the issue never came
up. The Mac OS X 10.8+ <setjmp.h> has the annotation, so it's probably
best to fix both while you're at it.

Can't hurt: I'll also run a i686-apple-darwin11 bootstrap which I can
use to verify it.
