 Sorry I used the wrong wording, what I meant to say is that it expects ioctl parameters
 using a different ABI than the one provided by system soundcard.h.
 My understanding is that using compat/ossaudio to support userland OSS applications
 on non-NetBSD systems would require writing an intermediate layer to do the ABI
 translation. And performing a few minor adjustments to libossaudio is much easier
 than writing an ABI conversion layer :-)
