IMHO such a wrong-code should be fixed also on 4.4/4.3.

FWIW, Ian's fix backports trivially to 4.4 and 4.3 and fixes this test case
there with no test suite regressions (all default languages) on i686-linux.

Actually there is a defect report against the C standard for this issue.

I take that back.  Note it worked for some previous versions of GCC.

This is a HWI issue as it works with --enable-target=all but fails without that
(--enable-targets=all changes HWI to be 64bits).
