What happens if you have the attribute packed on the structure? Then guess
what _Alignof should always return 1 for all types end of story according to
how you interrupt the C standard.
The alignment requirement for double is 8 end of story. But the alignment in
structures is 4. Those can be different as far as I can tell. And yes it is a
dup because of the same reason why GCC's alignof and _Alignof are the same and
are supposed to be the same.
