$NetBSD: patch-aa,v 1.16 2014/06/16 13:26:25 jperkin Exp $

ioctl() takes u_long argument on NetBSD.
On NetBSD<6 and 6.99.0-6.99.7, use third parameter in ioctl instead of varargs.
stat() system call has been versioned, use latest version when dlopen()ing.
Try more typical device names.
SOUND_PCM_* is not available on SunOS.
