  I just discovered that, too. :) Thanks for the tip, though. The
  detection did work with the modified configure, but it kicked out a
  bunch of errors on make.

  I do wonder about the defines mentioned in ALSA's source "NOTES" file,
  but no clue where they're supposed to go.

  If it helps, these are the errors when it tries to build ao_alsa9:

---
cc -c -O4 -march=i586 -mcpu=i586 -pipe -ffast-math -fomit-frame-pointer -D_REENT
RANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64  -I. -I..  -I/usr/local/include
     -o ao_alsa9.o ao_alsa9.c
ao_alsa9.c: In function `init':

Thanks again, hopefully this'll be ALSA's last API change!
