large login and idle times. This was due to a bug in utmp.c:
in os.h
-------
# define utmp utmpx
# define ut_time ut_xtime
in utmp.c::makeuser()
---------------------
struct utmp *u;
(void)time((time_t *)&u->ut_time);
The above works fine on i386 where ut_xtime and time_t are the same size,
but on sparc64 ut_xtime is 8 bytes rather than 4.
This fix was tested on i386 and sparc64.
