Having discussed this, I can understand that it may be desirable to
skip the permissions of the SYSTEM account in these circumstances:
- Computing the POSIX ACL mask and default mask value and thus in
the permission mask as printed by `ls -l'.
- Changing SYSTEM permissions when calling chmod, unless SYSTEM is the
file's owning group.
Changing this in the code is pretty straightforward. but I'm not willing
to add another mount option for this behaviour. Either Cygwin ignores
SYSTEM in the aforementioned circumstances or it doesn't.
Crucial vote starting... now.
