In Claw.Bitmaps there's a record with

    type Windows_Info is record
        ...
        Planes   : Claw.Word range 1 .. 1 := 1;

IIRC we noticed that we definitely needed the representation

        Planes      at 12 range 0 .. 15;

otherwise ObjectAda didn't leave any space, since it knew that Planes
was a constant always equal to 1.
