[Freeciv-Dev] contains_special type safe?

[Mike Kaufman <kaufman@xxxxxxxxxxxxxxxxxxxxxx>]

/***************************************************************
 Returns TRUE iff the given special is found in the given set.
***************************************************************/
bool contains_special(enum tile_special_type set,
                      enum tile_special_type to_test_for)
{
  enum tile_special_type masked = set & to_test_for;

  assert(0 == (int) S_NO_SPECIAL);

  /*
   * contains_special should only be called with one S_* in
   * to_test_for.
   */
  assert(masked == S_NO_SPECIAL || masked == to_test_for);

  return masked == to_test_for;
}

surely this can't be correct: enum tile_special_type set is in general not
an enum tile_special_type...
