Note that the gfortran on that page seems to be 32 bits only, so that
cannot work. But even if you use gfortran which targets 64 bits (from
mingw-w64), it will not work anyway, as linking VS 2008 and gfortran
together on 64 bits windows is tricky to say the least.

Two choices at least:
 - you actually do not need a fortran compiler at all to build numpy
(only needed for scipy)
 - if you still want to compile with fortran, then the only one known
to work at the moment is Ifort from Intel. I recently wrote how to
build numpy with VS 2008 and ifort on 64 bits with numscons on the ML,
look in the archive,

cheers,
