If you're trying to reproduce the exact permissions as Windows sees
them, you're out of luck with Cygwin.  The ACL handling in Cygwin is
using the Solaris view on ACLs, which is basically the same as the POSIX
view, just using a different API.  The Solaris/POSIX APIs handle only
three permission bits corresponding to the POSIX "rwx".  These are
mapped as useful as possible to Windows permission bits.  If you want
exact Windows ACLs, use native Windows tools.
