www.sciviews.org, though this benchmark caused a lot of work in octave 
and so the results presented there are out of date.

I'm not sure your benchmarks are fair, since you don't install either 
atlas or octave-forge, and I suspect FFTW either, under mingw. This can 
be seen in the relative values you give. The only benchmark value that I 
think is important in these in the Fibonacci test where cygwin wins, as 
this tests for-loops. Though this is with g++ 3.2 and the results would 
have been very different with a later compiler....
