Like it or not most of the world has turned into linux. We can either
provide compatibility where possible (and not overly disgusting) to
gain compatibility with 3rd party code developed for linux, or simply
say "tough, it will not work on NetBSD because we refuse to compromise".
It is a slippery slope, but I think in this case it is wise to bend.
If we cannot reach agreement here, consult core.
