The package System.Storage_Elements has the following function:
function "+"(Left : Address; Right : Storage_Offset)
  return Address;

If you change your code to read:
      function "+" (Left : in System.Address; Right : in Integer)
return System.Address is
  use System.Storage_Elements;
begin
  return Left + Storage_Offset (Right);
end "+";

You should do just fine.
