yet another posible m4 solution:
------------------8<----------------------------
define(DBP,`ifdef(`DEBUG',fprintf(stderr,$*))')

DBP("not printed %d",1); 
                      ^ unfortunately this "gets through" in both cases
define(`DEBUG')

DBP("printed %d%d%d",1,23,4);
DBP("so is this %s\n","string");
