Ultrix patches version 2 for bind 8.2.2-P3

[Simon Burge]

Another thing for Ultrix.  I had proposed changing

	if test ! -d ${THREADED} ; then mkdir ${THREADED} ; fi

to

	-if test ! -d ${THREADED} ; then mkdir ${THREADED} ; fi

but

	if test ! -d ${THREADED} ; then mkdir ${THREADED} ; else true ; fi

also works, and doesn't result in the unsightly

	if test ! -d threaded ; then mkdir threaded ; fi
	*** Error code 1 (ignored)

for every object file built.  This works for Ultrix make and BSD44
(well, NetBSD) make on Ultrix - any problems you can see with other
OSs?

Simon.
