381fe1aaf4 Make the LINT kernel compile with -W -Wreturn-type -Wcomment -Werror, and 
add same (sans -Werror) to Makefile for future compilations.

6f78ca6026 Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some 
minor cleanup.  Added $Id$ to files that did not have any version info, etc

e730ca26a3 Convert another printf into an lprintf since this should only be output 
for debugging.

Thanks Chris.

The only place I found with a printf("status %x") is in /sys/i386/isa/lpt.c,
and looks much like a left-over debugging printout...

And it was... I changed it to an lprintf (which is defined if debuggin is on)

0d01087b28 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.
