CVS does only really support _one_ vendor branch, even if some
docs say otherwise. So if the original gcc sources are on a vendor
branch, openbsd changes for examples should be imported on another
branch, and then explicitly merged (vendor branch is merged implicitly,
which is arguably a feature or a bug ;-)
