From Bruce Evans:
lpt doesn't work here if the printer is not turned on at boot time (this
has been reported for other systems).

lpt has a weird mapping of the flag bits vs printer numbers and MAKEDEV
does not understand this (printer 0 uses minor numbers 0-0x3f, printer 1
uses minors 0x40-0x7f, etc).

The following (simpler) problems are fixed by the patch.

lpt did not check the minor number on open, so if NLPT1 == 1 and you
try to open printer 1 then random memory above the lpt_sc array is
accessed.  I thought I had this problem for minors 1 and 2.  However,
it does not actually occur until minor 0x40.  Does anyone have lpt64?

lpt had several unnecessary && broken ANSIisms and other sloppy
declarations.

Bruce
