Here's the reason - you don't have a valid /etc/passwd and /etc/group file
installed yet, so cygwin does not know what Windows ACL to create.  See
http://cygwin.com/cygwin-ug-net/using-utils.html#mkgroup for details.

Also, you might be using a different filesystem than NTFS, although
following these directions, and attaching 'cygcheck -svr' output as a text
attachment, would have let us know for sure:
