Hi!

        No, only on BSD/OS.   FreeBSD has __FreeBSD__ for example.   I am not
        sure what other systems (such as NetBSD) have  - probably something
        like __NetBSD__.

        Oh, cool!   Are you using Joerg Schilling's generic scsi interface?

        'libdvd' is what translates the linux CDROM ioctl calls into generic
        SCSI commands for the kernel (which also works with ATAPI devices).

        Ah, that will be nice.  Tracking down that problem was the single 
        biggest challenge in getting vcdimager to run.

        Will a "per OS" 'cdrom image source driver' be needed?   Each system
        is different in how it accesses devices.   It may be necessary to
        use the 'libdvd' interface as the BSD/OS 'cdrom image source driver'.

        Indeed it is!   I needed to emulate the DVD/IOCTL functions so that
        ioctl(fd, CDROMREADRAW2, ...) behaved the same - what better guide 
        than the Linux cdrom.c? :-)

        Quite true ;)   For a long time I've been using a hacked version of
        0.6.2 - then I decided to give 0.7.9 a try a couple evenings ago.

        Thanks for the quick response - I appreciate it.
