Windows 64 is actually the easiest problem: you can find free trial
license for Windows server 2008 on MS website.
The main problem is the compiler and BLAS/LAPACK: mingw cannot target 64
bits yet (there is a mingw-w64 project, but after some digging, I found
out that it was legally dubious, hence not integrated yet in the 'real'
mingw project). Now, you could think about using MS compiler, but I
don't like the idea very much, and there is the problem of blas/lapack.
cygwin, already slow, is dog slow on windows 64 (because it runs in 32
bits, I guess ?), and is needed to build atlas (blas and lapack too, but
it is at least theoretically possible to build them without makefiles;
atlas build system is so complicated that it makes autotools feel
