If this is important enough for 'rmdir', I suppose you could patch it to give you the behavior you describe. But making Cygwin work this way internally is playing with the already complex path processing code. I can't see the gain to support this corner case and slow down everything else. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
