Now I remember that the 32-bit size of _Atomic_word came up when I
did the AIX port.

As far as I can tell from the errata, the syncs always are
necessary until the next rev of the PPC405. The existing syncs in
locks.h, which are necessary for MP correctness, do not replace the PPC405
syncs which need to be inserted before the stwcx., as far as I understand.
This patch looks really good to me.
Thanks, David
