[vorbis] libao: alsa plugin won't compile

[Murphy]

Hey'

Can't seem to compile libao.  I'm using Slackware-7.1-current-ish,
linux-2.4.2, gcc-2.95.2, and alsa-9.0-beta2.  This is the first time I've
tried to compile libao so I don't know if the problem is related to
alsa-9.0 changes.  

Alsa headers seem to be there:

/usr/include/linux> ls -l as*.h
-rw-r--r--   1 root  root  35994 Mar  3 10:57 asequencer.h
-rw-r--r--   1 root  root  31982 Mar  3 10:57 asound.h
-rw-r--r--   1 root  root  10435 Mar  3 10:57 asoundef.h

from config.cache:

ac_cv_lib_asound_snd_pcm_open=${ac_cv_lib_asound_snd_pcm_open=yes}

The compilation error:
