Considering you're the first one to have such a problem, I think the
precise compiler version you use matters here. Also the redundant
definitions shouldn't be different, and identical re-definition should
not yield a diagnostic. So I think there's a little more data you need
to supply in order to determine whether we need to adjust something.
