It makes sense -- if the following assertion is true for NT/2k/XP, as
well as more modern versions of Windows, for both cygwin-1.5 and cygwin-1.7:
Admins group access to a file (-...[rwx]... as specified by $2 if group
ownership of the file is Administrators, or a sufficient group token in
the extended ACLs is present as determined by getfacl) is necessary and
sufficient for the SYSTEM user (and/or the special privileged user) to
access the file, regardless of the file's actual owner.
