Just that the utility code that checks for extensions wasn't tested with
a machine that can do legacy free.  I've attempted to update the
extension-checking functionality to provide a legacy-free
implementation, but I don't have any machine with glGetStringi available
(i.e. I don't have a 3.x capable card), so I can't actually test that it
works.  If you can test with bzr head, it would be helpful.

HTH,
Mike
