Then, you can just use something like:

  debug(("%s\n","This is a test."));      (<===  This is an EXAMPLE; it's not
                                                 meant to be efficient, just
                                                 to emphasize the syntax!!!!)

in your code.  Just like printf(), except you need *two* parentheses around
the argument list.

I've been using this trick for years.
