I suspect that the root problem is that FreeBSD 9.1 lacks a working stdalign.h. Perhaps this is because they're implementing C11 gradually and added _Alignof before adding stdalign.h. Or maybe their stdalign.h fails the 'configure' test for stdalign. When implementing that part of Emacs I assumed that implementations that had _Alignof would also implement stdalign.h, but FreeBSD appears to be an exception. The change in trunk bzr 113322 removes the assumption that _Alignof is missing if stdalign.h is missing, so I hope it fixes this porting glitch. Strictly speaking this would be a bug in FreeBSD only if they're saying they support C11. If they claim only C99 support they're allowed to define _Alignof without providing stdalign.h. But in the long run they should provide stdalign.h so the problem would go away even without the bzr 113322 fix. I don't know whether the fix (once it's tested) is worth backporting to Emacs 24.
