 There's a big problem with using sys/compat/ossaudio on non-NetBSD: since
 it is built in the kernel tree, it includes the NetBSD version of <sys/soundcard.h>
 and also other headers like <sys/audioio.h> and <sys/ioccom.h>.
 
 As a result it can't be ABI-compatible with applications that were built
 using the system-wide version of <sys/soundcard.h>.
 
 Note that rebuilding world is not supported with binary-based distributions, unlike
 systems of BSD tradition where it's usually a trivial task.
