/usr/include/soundcard.h:#define ioctl(fd, com, argp) _oss_ioctl(fd, com, argp)
/usr/include/sys/ioctl.h:int    ioctl __P((int, unsigned long, ...));

soundcard.h gives you Linux OSS emulation.

Preferred way on OpenBSD is to use sys/audioio.h, which is the native
audio interface and generally best kept up-to-date.

slPortability.h tries to use OSS instead, however.

A simple workaround as follows. I guess you would have to have a
way to use OSS too under OpenBSD, though.

diff -uNr plib-1.2.0.orig/src/sl/slPortability.h plib-1.2.0/src/sl/slPortability.h

With CFLAGS set to include and link with /usr/local and /usr/X11R6/lib,
this should build under OpenBSD 2.8-current. Haven't yet tried
actually running anything with it, tho.

I guess I should update my XF to OpenBSD snapshot of XF4 and try
and compile plib against it while I'm at it.
