Hi Paul,

> I expect this is a GCC 4.7 bug

Yes, I confirm: I can reproduce it with gcc 4.7-20120121 built from
source. Since this is not a regression, it will most likely not be fixed
in time for GCC 4.7.0 [1].

I've updated the documentation accordingly:

        stdalign: Document the last change.
        * doc/posix-headers/stdalign.texi: Mention GCC bug 52023.

 This header file is missing on most circa-2011 platforms.
 Clang 3.0's @code{<stdalign.h>} does not define @code{alignof}/@code{_Alignof}.
