Hi folks,

	With help from Warren, I've found and fixed Minix's 
'isoread' utility so that it works under 2.11BSD.  I've tested
it on my 11/73 with an Andromeda SCDC and TEAC SCSI CD-ROM
drive, and it works fine.  Shortly I'll test it with my
CMD CQD-440 and Emulex UC08 host adapters on my Q-bus systems,
as well as my CMD CDU-720 on my Unibus -11's.

	To keep things brief, here's the 'diff' output between
the Minix 2.0.0 'isoread.c' and the 2.11BSD 'isoread.c'.  The
changes are minimal: a small change in the includes, the appropriate
_PROTOTYPE macro, and using L_SET instead of SEEK_SET in the
single lseek call:
