/* We would like to use some performance benchmarking as a way to determine
    if ajc is or is not generating the code for dynamic join points in all 
    cases except for m4().  However, HotSpot is too smart for us today, and
    manages to optimize this away.  Since the point of this code is that
    such an optimization is possible, I'm not sure that we can write a test case
    for this...

   So, this test case doesn't do all that good a job.
