Regardless of clang's support (and clang has a different set of
supported attributes than GCC), the __attribute__ stuff is not part of
any standard whatsoever and is therefore untrustworthy. It only exists
because #pragma hadn't matured, and clang only supports it because it is
trying to be compatible. It would be better to find a different way.
