That's a result of a specific setting you tried with chmod.
I suggest reading the ntsec chapter in the online documentation

	http://sources.redhat.com/cygwin/docs.html

especially the chapter about the `mapping leak'.
The ability to create such settings which aren't supported
by the Windows GUI are a intended design decision. However,
note that such ACL's are correctly identified by the NT/W2K
kernel, it's only the GUI which lacks support.

There's no need to use ntea if ntsec is on. ntea is only an
emulation of UNIX permissions which are completely opaque
against native Windows apps.
