The utmp (and now perhaps wtmp) stuff could be very useful for
other people as well.  Does breaking the code out into
a separate package univeral utmp and wtmp library make sense?

Perhaps some autoconf macros and Makefile fragments to make it
easier to have it work on any system and be integrated easily.
