Ok.  I've been having a try at mingw-w64 project:


with no success so far with build numpy:

$ python setup.py build --compiler=mingw32
Found executable C:\mingw-w64_x86_64-mingw\mingw64\bin\gcc.exe
g++ -mno-cygwin _configtest.o -lmsvcr90 -o _configtest.exe
Found executable C:\mingw-w64_x86_64-mingw\mingw64\bin\g++.exe
../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lmsvcr90
collect2: ld returned 1 exit status

However, I can compile it with plain mingw tool chain (obviously, only can get 
w32 binaries).  Any hint on how to proceed with mingw-w64?
