Yes, use acl_xattr to store the windows acl if you want that handled
faithfully.  The last ACL to be set will win. 

If you set a POSIX ACL then any windows ACL that has been set will be
ignored.  If you set a windows ACL on the same file then it will be
translated into posix and also stored.

So, the idea is that it would 'just work'.
