(* Just to warn me when there is some news in the types in
 * ast_cocci.ml or even ast_c.ml, so that I can then adjust my code in
 * pattern.ml or transformation.ml.
 *
 * For the moment I do it only for myself (pad), that is I check only
 * for news in ast_cocci.ml, because I already know when I add stuff in
 * my code in ast_c.ml or control_flow_c.ml. *)
