Technically, this is a Mesa bug, so I'm not sure if a PR is appropriate
here or not.

There is a reported bug with Mesa 6.0 on Tru64, over on the SourceForge
Mesa project page.

I have what appears to be the same problem on NetBSD/amd64.

Just a FYI.  (Their buglist is short, so if you want to see the
details, just browse for Tru64 in the list, I believe.)
