This is probably a WONTFIX, but after actually finding one occurrence, I think this should be pointed out. In bug #259228, I have reported a QA Notice for dev-lang/ocaml. Portage prompts to file a bug report upstream: * Please do not file a Gentoo bug and instead report the above QA * issues directly to the upstream developers of this software. * Homepage: http://www.ocaml.org/ The warning does not appear in vanilla ocaml sources. It only appears after applying a Gentoo specific patch. I do not know if this will still have to be fixed upstream, but in any case this should be first reviewed by a Gentoo maintainer. So prompting to report upstream is misleading. Of course, this happens only very rarely. But asking a user to bother upstream with invalid reports is never a good idea. :)
It's not possible for code that generates warnings to know whether or not the problem has been triggered by gentoo-specific patches. Cases like this should be sufficiently rare that qualifying all of the the warning messages with a note about gentoo-specific patches would be overkill.
