wmcdplay: Port to FreeBSD.
As is, wmcdplay does not build on FreeBSD systems. Although it has since been deleted, a port of wmcdplay for FreeBSD was available. It consisted primarily of a patch to cdctl.h [1]. Include this patch when building for FreeBSD. Based on the Debian patch [2]. [1] https://svnweb.freebsd.org/ports/head/audio/wmcdplay/files/ patch-aa?revision=56594&view=co&pathrev=56594 [2] http://sources.debian.net/src/wmcdplay/1.0beta1-13/debian/patches/kfreebsd_port.patch/

// application never sees it.

// Verdict: Linux audio cdrom handling is broken.
