DESCRIPTION
       The explain_setuid_or_die function is used to call the setuid(2)	system
       call. On	failure	an explanation will be	printed	 to  stderr,  obtained
       from the	explain_setuid(3) function, and	then the process terminates by
       calling exit(EXIT_FAILURE).

       The explain_setuid_on_error function is used to call the	setuid(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_setuid(3) function, but	still returns to the caller.
