the first thing to check is whether main.o uses the symbols from
utempter. These are used in the configure check:
addToUtmp("/dev/tty", 0, 1);
removeFromUtmp();

actually, the checks for setuid/setgid behavior are a more promising
place to look for a lost ifdef - looking at the ones in main.c for
"USE_UTEMPTER":
#if defined(USE_UTEMPTER)
#if defined(USE_SYSV_UTMP) && !defined(USE_UTEMPTER)
#ifndef USE_UTEMPTER
#endif /* !USE_UTEMPTER */
#if defined(USE_SYSV_UTMP) && !defined(USE_UTEMPTER)
#if (!defined(USE_UTEMPTER) || !defined(DISABLE_SETGID))
#if !defined(USE_UTMP_SETGID) && (!defined(USE_UTEMPTER) ||
!defined(DISABLE_SETUID))
#if defined(HAVE_POSIX_SAVED_IDS) && !defined(USE_UTMP_SETGID) &&
!defined(USE_UTEMPTER)
#if defined(HAVE_UTMP) && defined(USE_SYSV_UTMP) && !defined(USE_UTEMPTER)
#ifndef USE_UTEMPTER
#endif /* !USE_UTEMPTER */
#if defined(HAVE_UTMP) && defined(USE_SYSV_UTMP) && !defined(USE_UTEMPTER)
#if defined(USE_UTEMPTER)
#ifndef USE_UTEMPTER
#endif /* USE_UTEMPTER */
#ifdef USE_UTEMPTER
