- Implement BasepOpenFileForMove() used by PrivMoveFileIdentityW(), with its Windows bugs - Implement PrivMoveFileIdentityW() Not sure yet why Windows implementation exposes a sharing violation during our API test. Our absence of sharing violation looks more legit... To be investigated. svn path=/trunk/; revision=67335
