Comment:

 Matthias, can you comment? I know that the P^2^ algorithm requires *far*
 more samples that is being provided here for any reasonable accuracy, but
 I can't fathom why the result should be different for different
 optimization levels. I don't believe gcc does unsafe floating point
 optimizations unless you specifically tell it to. Or am I mistaken about
 that?
