Yeah.  Richi pointed out in the review that we could just use a GCC plugin to
test it, so I've got a patch for that going through internal review.  Using a
plugin is much nicer because it doesn't depend on a non-default language or on
fixed-point support.  It also means we can test the wi:: routines directly (in
addition to the Ada testcase, which I'll still commit).
