As others have pointed out already, you can use the "noacl" option to mount
paths and drives to use Windows ACL semantics instead.  You can even mount
'cygdrive' with "noacl" so that all references to drives through "/cygdrive"
will follow the Windows semantics.  If you're looking for the finer details
and caveats about how POSIX ACLs are used and not, see the section on "The
Cygwin Mount Table" in the User's Guide:
