Hello.
On Mac OS X 10.6, driver_osx.c build fails with message below.

I made a patch. But I didn't test yet, because initialization error
below occured.

I have googled the Apple proprietary library error measseges
and I guessed this is a matter on Snow Leopard (Mac OS X 10.6).
As far as I know, there is not any document about the new library.
(I am a member of Apple developer connection.) So I can't debug
this any more. This patch solves compilation error only.
