Ack, that needs fixing for amd64 etc. The rest worked for us...

FWIW, Robert, DieHarder's principal author (CC'ed), works on a Fedora system, and we know of successful ports to (at least) BSD. So unless you tell us how it fails there is little we can do.

Excellent! I had one quick look a few month ago on my MinGW setup at work and ... didn't have enough (and interest) to make it work. But having a working RDieHarder on Windows would be very useful, so thanks!

I look forward to receiving those. We also got patches from Anton Korobeynikov (CC'ed) for building DieHarder on Windoze but I haven't had time to look at those.

Thanks, Dirk
