This looks sane. I'll get it applied to HEAD.

I should have said, following your e-mail the other day, that the repository
you were using was the right one to work on. Patches should initially be applied
to HEAD and then backported to branches as necessary. We don't want to end up in
a situation where patches are only on a release branch (effectively, a dead end).

Ah, I think the problem here is there's only aix, linux, macosx, solaris and
windows in that directory. HotSpot, however, has BSD...

It seems some of the BSD port has been included upstream but not all. Let me
see if I can bring in an appropriate file from the BSD tree.
