As i mentioned in private mail:
	(1) we don't define _POSIX_SAVED_IDS,
	(2) because of that, you can't switch back and forth
		between real uid's.
	(3) there is NO posix interface that allows you to
		just set the real uid.

given that, your only options are the BSD extensions to POSIX,
which allow you to swap the effective UID...

why are you so keen to have the _real_ uid set, in any case?
for everything except access(), the effective UID is used
for determining stuff like permissions...
