Committed. We don't have gcc-4.3 or icc in 1.12 so I don't think this needs
to go in the release branch (but if it did, the correct way to do it would
be with "cvs commit -r DragonFly_RELEASE_1_12 [files]", right? Sorry, but
I haven't used cvs for development since the first free software distributed
scm became available[*], so perhaps there's an extra quirk I don't remember
about?)
