- *      static VOID ChangeOwner(pathname)
- *
- *  DESCRIPTION
- *
- *      For unix systems, change the owner of the newly created debug
- *      file to the real owner.  This is strictly for the benefit of
- *      programs that are running with the set-user-id bit set.
- *
- *      Note that at this point, the fact that pathname represents
- *      a newly created file has already been established.  If the
- *      program that the debugger is linked to is not running with
- *      the suid bit set, then this operation is redundant (but
- *      harmless).
