1) I am hardly a C language lawyer, but I can't recall a portion of
the standard where this would be mandated.

2) Clang behaves differently (Clang 3.2, Linux x86_64):
———
   9  .globl s, at OBJECT,COMMON,ALIGN=4,SIZE=16
  10  .globl x, at OBJECT,COMMON,ALIGN=4,SIZE=4
———

3) __alignof(struct S) is (obviously) also 4 for GCC.

I still think that int4 could be an alternative for situations where
you need the extra alignment guarantee, but my main request is that if
you want to keep the test in, that behavior should be reflected in the
spec, so it can be implemented in GDC/LDC without guessing what was
being meant.
