Not always.

The core problem is that the semantics for file deletion are different 
on Windows than on *ix, and some *ix programs depend on this in ways 
that make them fail on Windows.  The new Cygwin file delete code uses a 
feature of Windows specifically introduced to work around a consequence 
of the Windows delete semantics in order to fake *ix semantics as well 
as you can reasonably expect.

I think the new feature is great, and don't want to see it go.  It's a 
clever solution to a real problem and fits Cygwin's mission perfectly.
