The compress program, as distributed, can be made to work on 16 bit
processors by defining M_XENIX to the compiler when making compress.
If this is done in IBMFLAGS it will make compress OK but it will kill
the other compiles on a USG (Simul-Task, Microport) system.  To have
it work across the board change line 291 of Makefile.dst from
    $(CC) $(CFLAGS) $(LFLAGS) -o compress compress.c     to read
    $(CC) $(CFLAGS) $(LFLAGS) $(I286) -o compress compress.c
now add a line after line 61 that reads
#USG I286 =
and put a line in your localize.sh for the Makefile that reads
/^I286/s/$/ -DM_XENIX/

If you are content with 12 bit compression you can localize with
/^IBMFLAGS/s/$/ -Dpcxt/
but be sure that your neighbors compress for you with -b12, that can be
forced in the sendbatch script.  If you feed news to a 16 bit site that
didn't make compress for 12 or 16 bit mode (first fix) be sure that you
set cflags to -b12 in the sendbatch script.

I suppose I should have made this in patch form but I'm not sure how to
do that and I didn't want to experiment with "live data".  This is sure
to bite anyone running AT&T Simul-Task or Microport System V/AT.
