Thanks Mark, also thanks to DJ again.

Mark, if you don't think it is worth the affort I won't spam this
mailing list anymore. Upcoming versions of Windows intend to be x64 only
(no more 32-bit). So I thought it would be interesting to have some
support for those platforms before the release...

However I would keep on trying if I had enough free time.

For now I switched back to 32-bit, as you advised.

Regards, Andreas

BTW: 64-bit JVM is as slow/fast as 32-bit JVM on my machine.
