gets invoked in which platform is simply a big mess that needs to be
untangled. Secondly, the effects are apparently not standard across
platforms, (if you first set $< and then $>, or vice versa, being
-uid==euid== zero, or just euid==zero, or as a normal user, what are
+uid == euid == zero, or just euid == zero, or as a normal user, what are
the results?). The test suite not (usually) being run as root means
that these things do not get much testing. Thirdly, there's quite
often a third uid called saved uid, and Perl has no knowledge of that
back any real and effective uids.) As an example, to change also the
saved uid, one needs to set the real and effective uids B<twice>-- in
most systems, that is: in HP-UX that doesn't seem to work.
