Nothing at all. :-)

Hang on. If you're writing your own compiler and it is on the shootout then 
you can just substitute and interpret until all of the trivially flawed 
shootout tests (ackermann, binary trees, dispatch, harmonic, mandelbrot, 
n-body, nsieve*, pidigits, random, spectral-norm, startup and takfp) are 
completely optimised away.

That should boost Felix' rankings. :-)
