Try pragma Warnings (Off) and (On) round the representation clauses.
In fact, this works for me (GCC 4.3.0):

   for T1 use
      record
	 pragma Warnings (Off);
         Version at 0 range 0..1;
         Inline  at 0 range 2..2;
         Command at 0 range 3..7;
	 pragma Warnings (On);
      end record;
