Unexpected "setfacl: illegal acl entries"

Greetings, All!

I'm receiving this unexpected message when trying to edit the directory ACL:

>> [C:\Programs\Cygwin\bin]$ setfacl -m user::rx .
>> setfacl: illegal acl entries

But then I'm trying this

>> [C:\Programs\Cygwin\bin]$ setfacl -m user::r-x .

and it succeed.

To the all of my knowledge, ACL bits can be specified in any set or order.

Even the `setfacl -m user::wXr` command is correct.
