Could you re-post the patch in this ML (if you think it should be applied to bdwgc)?

Libatomic_ops should either be handled as a separate package, or should just use GC version numbers.  And I think the former option requires more work for which we're currently lacking volunteers.

Nonetheless, I've committed the rename. I don't think having such an artifact is good - the hard-coded version, e.g., may make someone think bdwgc can work only with a particular libatomic_ops version. The cvs version numbers start from 1.1 but the old numbers and log history is in the old place - the only inconvenience is diff across rename (same as for libatomic_ops-1.1 to libatomic_ops-1.2 rename).
