History:
Modified by cmetz for OPIE 2.4. Add support for ut_id and
ut_syslen. Don't zero-terminate ut_name and ut_host.
Modified by cmetz for OPIE 2.31. If the OS won't tell us where
_PATH_WTMP[X] is, try playing the SVID game, then use
Autoconf-discovered values. Fixed gettimeofday() call
and updwtmpx() call. Call endutxent for utmpx. Added
DISABLE_UTMP.
Created by cmetz for OPIE 2.3.
