I found the cause of these problems. It turned out that
	/usr/include/whoami.h
was out of date (it was the original file from the boot-tape).
Doing
	cp /usr/sys/MYMACHINE/whoami.h /usr/include
and then recompiling adb and ps made the problems go away. As some of the
responders pointed out:

	Make sure that
		/usr/sys/MYMACHINE/whoami.h
	is identical to
		/usr/include/whoami.h

	and that
		/usr/sys/MYMACHINE/localopts.h
	is identical to
		/usr/include/sys/localopts.h

My thanks to all who responded.
BTW: We previously run a more or less vanilla v7 on this machine. 2.9BSD
makes quite a difference. My compliments to Berkeley for producing this
marvelous piece of software. My only gripe so far is that identifiers
in C are still only significant in the first 7 characters. On the other
hand: you get job control and UCB_SCRIPT and symbolic links and overlays
and ... Hot dog!
