If you have root permissions on your system, you should be able to use the
'unlink' command to solve this one.  (Note:  I have just created and solved the
problem you described on my SCO XENIX 386 2.3.2 system, SVR2 + BSD stuff)

Here is what I would do:
(assume /tmp/junk is the dir to be deleted, /tmp/junk/oops is the recursion)
login as root.
cd /tmp/junk
ls -lia
(which produces:
total 8
 4302 drwxr-xr-x   3 bob      pds           48 Feb 24 13:29 .
   19 drwxrwxrwx   3 bin      bin         1616 Feb 24 13:29 ..
 4302 drwxr-xr-x   3 bob      pds           48 Feb 24 13:29 oops
)
unlink oops
ls -lia
(which now gives:
total 6
 4302 drwxr-xr-x   2 bob      pds           48 Feb 24 13:30 .
   19 drwxrwxrwx   3 bin      bin         1616 Feb 24 13:30 ..
)
cd
rmdir /tmp/junk


Hope this helps!
