Perl 3.0 t/op.mkdir: print ($! == 17 ? "ok 3\n" : "not ok 3\n");

[Jan B. Andersen]

Test 3 in op.mkdir fails.

I seem to recall someone mentioned this before, but I don't remember
what the solution was.

This is on a NCR Tower Sys V.2 machine. I have #undef'ed some of the
directory and password stuff in order to compile Perl.
