Or maybe, slightly reducing the intended effect of the change, limit
the warnings to the case where the value isn't representable when
considering it unsigned nor when considering it signed? I think that
would at least take care of all the testsuite failures (but it would
leave in place brokenness for certain consumers, including nm).
