Could you compile the program below on that box and send me the output ?

Cheers,
Bill.

#include <math.h>
typedef unsigned long ulong;
main()
{
    ulong a=18446744073709551431UL;
    double beta=sqrt((double)a);
    double p=beta*(1UL << 32);
    ulong u = (ulong) p;
    long l= (long) p;
    printf("beta=%g\np=%g\nu=%lu\nl=%ld\n",beta,p,u,l);
    return 0;
}
