I am using VS Express 2010 plus the Windows SDK. It seems to work. It
is possible to generate 64 bit binaries on 32 bit machines, BTW (with
cross compiling).
I have made some very simple changes to setup.py :
They should only impact Windows with 64-bit interpreters. Even if they
do not work (which they seem to do), they should only break 64-bin win
interpreters (which are not functional anyway).
