But that conflicts with Windows semantics, doesn't it?  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.
