    Okay, the thread is quite old, but I thought it might be interesting to see what this little proggie might do on a more modern iMac8,1 with a 3.06 GHz Core 2 Duo. Program compiled with "gcc -O3 bench.c -o bench" (removed the system function call):
    Code:
    $ gcc -O3 bench.c -o bench
    $ ./bench
    execution time for integral = 1e-06 seconds
    execution time for prime = 1.73697 seconds
    execution time for Goldbach = 6.28933 seconds
    execution time for dynamicfnc = 0.605303 seconds
    total execution time = 8.63174 seconds
