It can happen that users put the call to MSG_config before the one to MSG_init (hello Pedro ;). Check this and fail gracefully in that case. A yet better solution would be to initialize stuff in that case, but MSG don't like getting arguments (through MSG_init) after it's initialized so it seems really hard
