Now I have some problem for creating a win64 package using mingw-w64
targeting for either win32 or win64 machine, maybe as you said that
distutils isn't flexible enough, since I found that it could only accept
some popular compilers but mingw-w64 excluded. I wonder that can
numpy-vendor do this work, or is there any other way? I have seen some
unofficial win32 and win-amd64 binaries, and I wonder how they make it.
With msvc flag on win 64 machine?
Thanks a lot, Ralf.
