2.11 news under Tandy SCO XENIX 386 2.2.6

[Mike Squires]

Under Tandy SCO XENIX 386 2.2.6 (sold only by Tandy, has SCSI drivers)
using the 2.2 development system 2.11 news compiles without problems.
If VP/ix 1.1 is installed the file /usr/include/sys/machdep.h is refernced
in two different places in visual.c and virtterm.c.  I created /usr/include/
sys/ioctl-news.h without an include for machdep.h and continued.

Has anyone used XENIX GT on the 4000LX yet?  I have an upgrade on order,
but it's taking quite a while to get it.
