DG/UX Port Patches -- second attempt

["Eric Raskin" <ehr at listworks dot com>]

Jeffery:

  Here is the revised set of DG/UX patches with minimal changes, as you
requested.

  There are four separate attachments:

	1)  ChangeLog			Already supplied to you
	2)  t-dgux			Already supplied to you
	3)  dgux.h			Changed as little as possible
	4)  dgux.mt			Required for libio build -- not sure if I sent this before or
not.

  With these patches (using standard DG/UX assembler and linker), I only get
failures on weak symbol redefinitions.  Everything else seems to work.

  BTW, no one is clear on whether patches should be sent as attachments or
in the message, so I've done both.  Please add this to contribute.html for
the future.
