If you were able to get Mr. Masaglia's 8 RNGs, then you can download his
Diehard.zip that contains his RNG tester. It does run under windows in a
DOS window. Then, you can create a set of random numbers to from
Euphoria's RNG and feed them into it and we will all know whether RDS's
random function creates reasonably random sequences. If it does, you
won't need to convert any of that C code.
