Currently scipy binaries are build with MingW 3.4.5, as far as I know, which includes g77. The latest release of MingW uses gfortran, gcc 4.4.0 I think, that, eventually, scipy should switch to gfortran also on Windows. But it might need some compatibility testing. And it would be very useful if someone could provide the Lapack/Atlas binaries, similar to the ones that are on the scipy webpage for mingw 3.4.5. (I don't have a setup where I can build Atlas binaries). I haven't switched yet, but, given some comments on the mailinglists, it looks like several windows users are using gfortran without reported problems.
