That's the major difficulty: no open source blas/lapack (that I am aware
of) are buildable with MS compilers, and there is no official open
source compiler (mingw) on 64 bits. Also, cygwin itself is not available
in 64 bits (only available on WOW, the windows subsystem to run 32 bits
on 64 bits OS).

Atlas, in particular, is not buildable for 64 bits windows AFAIK.

I did some heavy refactoring for the above problems, and it should be
now easier to handle (in the trunk). I could build 1.2.0 with VS 2008
express on 32 bits (wo blas/lapack), and there are some test errors -
albeit relatively minor at first sight. I have not tried on 64 bits.

cheers,

David
