As the testcase fails with buggy (pre r144598) gcc and succeeds after even
with:

>     unsigned int fore : 12;
>     unsigned int back : 6;

instead of :9, :9, I think we could change it (does it succeed on picochip
then)?  Or move to gcc.dg/torture/ and run only on int32plus targets.
Or add if (sizeof (int) != 4 || sizeof (struct D) != 4) return 0
to the beginning of main.
