That would mean __alignof__(foo.b) == sizeof(foo.b) but that's not the

struct baa {

long long b;

That struct is just 12 bytes for you then?
Right. i686 and m68k agree on that.
On i686 (i.e. gcc -m32 on amd64):
__alignof__(long long) = 8
but
sizeof(struct baa) = 12
__alignof__(struct baa) = 4
???
Isn't the alignment of a struct the largest alignment of any of its members?
