This means we would have to give up any hope of supporting
cross-compilation with Interix as the target, or for that case simply
configure a known-working limit.   If we take the second option, we'll
have a limit that only applies in the cross-compilation case, which is
likely to produce an obscure bug further down the road.    I would
rather not leave any rarely-exercised cases at all.
