Does that mean "if sys/soundcard.h was found,
we are on a system where we want to use OSS"?

With that typo fixed, ./configure on OpenBSD thinks that
OPTIONAL DEVICE DRIVERS
ao (Xiph)..................no
alsa (Linux)...............no
coreaudio (Mac OS X).......no
sndio (OpenBSD)............yes
oss........................no
pulseaudio.................no
sunaudio...................yes
waveaudio (MS-Windows).....no
and the compilatiopn fails as in my previous email.
But ./configure --without-sunaudio results in
OPTIONAL DEVICE DRIVERS
ao (Xiph)..................no
alsa (Linux)...............no
coreaudio (Mac OS X).......no
sndio (OpenBSD)............yes
oss........................no
pulseaudio.................no
sunaudio...................no
waveaudio (MS-Windows).....no
and it builds fine.

Right; sorry for the confusion.
