354 **  - setuid/setgid file permission bits exist but have no-op functionality
356 **  - setuid() forces a gid change to the new uid's primary (and only) gid
367 **  setuid() in order to implement the following model:
369 **  - the sendmail program thinks it is a setuid-root (uid 0) program
371 **	- MPE priv mode allows sendmail to call setuid(), not uid 0
376 **  setuid mode bits which exist but are unused by MPE.  If the setgid mode
377 **  bit is on, then gid emulation will be enabled.  If the setuid mode bit is
468 **	if the setuid bit is on, we want uid emulation and so set
527 **	a setuid-root program.
553 **	Note that sendmail will also be calling setuid() which will force an
584 **  SENDMAIL_MPE_SETUID -- shadow function for setuid()
586 **	setuid() is broken as of MPE 7.0 in that it changes the current
588 **	we must obtain the cwd and restore it after the setuid().
