Thanks, that suggestion sounds like a good idea. It should address the issue in
the strerror_r.i and emacsclient2.i examples, which is a good sign. Although it
wouldn't handle the strerror_r4.i example, that is a special case and arguably
it's worth the hassle of suppressing the diagnostic individually for that case.
