Stupid System V Machines

Some ac's on System V machines (I've tried SGI Indigo & SGI Indy) forget to pay attention to the ut_type field in a struct utmp. As such, they chalk up a lot of time to non-existant processes called LOGIN or runlevel.

TANGIBLE RESULT: The amount of total time reported by the system's ac is really off. Often, it's several times greater than what it should be.

SOLUTION: GNU ac always pays attention to the ut_type record, so there's no possibility of chalking up time to anything but user processes.
