History:
|
|
|
|
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.
