X11R4 under Ultrix 4.0 (xterm, mfbpmax, cfbpmax)

[George Hartzell]

I just got done building X11R4 under Ultrix 4.0 on my color
DECstation3100, and thought I might share what I learned since I
haven't seen some of it on the net before.  I've been running this for
a day or so and it seems to work.

I've seen one anomaly that I haven't been able to repeat reliably.
Usually the load on the DECstation when someone is using the console
but not actively doing anything hovers around 0.  Twice now I've
caught it idling at about .4, with cfpmax being the only thing
apparently using time.  If anyone else sees this or knows what might
be causing it I'd like to know.

Here are my changes:

[I've seen this mentioned on the net already but am including it for
completeness]  DEC changed the definition of "fileno", requiring the
following changes to two files in the xterm directory.

  		/* mark this file as close on exec */



[I haven't seen this mentioned on the net yet]  DEC rearranged some of
the names and locations used in the code for the mono and color
DECstation servers.  Here are the patches.
