Right. Well, it compiles and runs just fine on my machine when I replace
portaudio/pa_mac_core/pa_mac_core.c with the new one and recompile. I'm
just using my normal internal sound driver, though. Best I can say is "it
compiles, and it doesn't seem to break anything obvious."

These are the changes since the last pa_mac_core.c synched with Pd:

 02.03.2003 - Phil Burk - always use AudioConverters so that we can adapt
when format changes.
              Synchronize with device when format changes.
 02.13.2003 - Phil Burk - scan for maxChannels because FormatMatch won't
tell us.
 03.05.2003 - Phil Burk and Dominic Mazzoni - interleave and deinterleave
multiple
              CoreAudio buffers. Needed for MOTU828 and some other N>2
channel devices.
              See code related to "streamInterleavingBuffer".
 03.06.2003 - Phil Burk and Ryan Francesconi - fixed numChannels query
for MOTU828.
              Handle fact that MOTU828 gives you 8 channels even when you
ask for 2!

Pablio and pa_common have also changed recently, but I haven't messed
with them, being as conservative as possible with changes.


What should I do?
1) Check in the new pa_mac_core.c and let curious people compile the
devel_0_36 branch?
2) Point people to the portaudio tarball and let them experiment with the
sources themselves? <http://portaudio.com/archives/pa_snapshot_v18.tar.gz>
3) Seed a new pd/bin/pd binary to people who want to test the updated
portaudio stuff with a range of hardware?
