You should implement a central "message dispatcher". So all errors etc. should go to someting linke
rome_msg(). If compiled with midas online support, rome_msg() should call cm_msg(). If rome is compiled
without midas libraries, a printf() there would be enough. If someone uses rome in a different
environment, only can function needs to be changed to reroute all messages to somewhere else.
