Only runtime wisdom - Will didn't put tunefftw.c in the distribution.
If you or Will can send me a copy I'll try the tests again.

Yes - two processors. Otherwise there would have been a MacLucasFFT16
or somesuch!

I've kept a not-very-close eye on fftw, and wrote a simple fftw-based LL
tester about two years ago, but used fftw and not rfftw. For reference,
it's at ftp://melanoma.cs.rmit.edu.au/pub/simonb/fftwll.tar.gz.
