    1 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?
