stdalign: port to stricter ISO C11 ISO C11 says that _Alignof's operand must be a parenthesized type. Problem reported by Eli Zaretskii in <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00960.html>. * doc/posix-headers/stdalign.texi (stdalign.h): Document this. * m4/stdalign.m4 (gl_STDALIGN_H): Don't use _Alignof (expr).
