Portable programs have specifics to each OS that it can be compiled on.  Why
do you think some portatble programs use automake?  Not ever OS defines
variables the same way or uses them the same way as others.

You are going to have to realize that accessing devices directly under
different OSes will require different code.  I've read all the stuff you've
posted and it is apparent that you want all OSes to use the scsi scheme.

I don't use cdrecord much anymore since 1) I have a DVDRW and 2) I burn
DVDs mostly.  It happily uses /dev/<whatever> instead of compilaining that
it's unintentional.

As far as I can see, you can use scsi ioctls on regular devices so why do
you really need to use the 3 numbers?  To find the right /dev/sg and use it? 
Doesn't make sense.  I looked at the eject program one day.  The IOCTL used
to eject a cdrom is different than solaris.  Gee, I guess eject is not
portable.  You should probably write a library that deals specifically with
each OS.  I don't ever see something like this being portable.  Especially
between a Unix environment and a Windows environment.

P.S. This is the first and will be the last time I post on this thread.  I'm
not trying to flame anyone, this is mostly an enduser observation.  The
native OS device usage should be used instead of something supposedly
portable.
