[Openal] Broken Doppler in OS X?

[E. Wing]

I noticed that my bug report with Apple on the Doppler problem was
recently closed. I was wondering if this means the problem was fixed
and if those changes have migrated back to the publicly available
version of OpenAL. (My bug report was against Tiger since they are
officially responsible for that one.)

 Thanks,
Eric
