That’s ① GCC-specific and ② relies on environmental guarantees
that cannot always be given (e.g. you cannot align a struct
more than the stack alignment if it is ever passed on the
stack; for static or auto storage, it relies on the linker;
for malloc, it relies on libc).

The approach here is not to make the struct aligned, but
rather, to make it consistent within itself. In a portable
way, even (although we do use GCC 4.9 on Debian/m68k).
