On SysV, a process can do chown/chgrp to any file which it owns (or which
belongs to its effective group ID). What tar does is to create the file
(which belongs to the user who ran tar) and chown/chgrp if the 'o' flag
wasn't specify. So in that matter, Irix is not different from other SysV-
based UN*X'es.
