The software contained here is based on the ancient Beta 1 release of X11.
Don't even bother starting with th dix contained here.  Also, the os/msdos
should probably be rewritten to simply emulate the 4.2bsd interfaces so that
the os code in the sample server can be plugged in as is.  The ddx interfaces
have changed, but not unrecognizably.  The hope is that the documentation and
some of the pc-specific code (esp. assembler code for device drivers) might be
useful. 

This version of xpc will NOT be distributed in further releases and should be
looked upon as a special exception to the rule that contributed software ought
to work on at least one relatively modern platform.
