-Subject: add max_align_t definition for C11 and C++11
-
-unfortunately this needs to be able to vary by arch, because of a huge
-mess GCC made: the GCC definition, which became the ABI, depends on
-quirks in GCC's definition of __alignof__, which does not match the
-formal alignment of the type.
-
-GCC's __alignof__ unexpectedly exposes the an implementation detail,
-its "preferred alignment" for the type, rather than the formal/ABI
-alignment of the type, which it only actually uses in structures. on
-most archs the two values are the same, but on some (at least i386)
-the preferred alignment is greater than the ABI alignment.
-
-I considered using _Alignas(8) unconditionally, but on at least one
-arch (or1k), the alignment of max_align_t with GCC's definition is
-only 4 (even the "preferred alignment" for these types is only 4).
