The biggest problem is that officially, there is still no gcc 4 release
for mingw. I saw a gcc 4 section in cygwin, though, so maybe it is about
to be released. There is no support at all for 64 bits PE in the 3 serie.

I think binutils officially support 64 bits PE (I can build a linux
hosted binutils for 64 bits PE with x86_64-pc-mingw32 as a target, and
it seems to work: disassembling and co). gcc 4 can work, too (you can
build a bootstrap C compiler which targets windows 64 bits IICR). The
biggest problem AFAICS is the runtime (mingw64, which is indeed legally

I would say that if you can build python by yourself on windows, you can
certainly build numpy by yourself :) It took me quite a time to be able
to build python on windows by myself from scratch.
