Compiling the following with Gnat 3.13p gives:


package P is

  type  T  is ('a', None, 'Z');
  type F_T is access function return T;

  X: F_T :=3D 'a''Access;
  Y: F_T :=3D None'Access;

end P;

     6.   X: F_T :=3D 'a''Access;
                    |
        >>> prefix of "Access" attribute must be aliased

Is this then a bug?
