Under SCO XENIX System V, a "who -Hq" produces the following output.

carmen carmen carmen
# users=3

I don't know about SVR4, but I do belive that the XENIX binary is
derived from SVR2 source.  It's a bug in the code, not functionality.
If the q option worked properly, the ability to also specify the H
option (or any other, for that matter) would "make sense".  The XENIX
man page states the following.

-q	This is a quick who, displaying only the names and the
	number of users currently logged on.  When this option
	is used, all other options are ignored.
		 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Which vendors port of SVR3 are you using?
