Ok. I've been having a try at mingw-w64 project:
http://mingw-w64.sourceforge.net/
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
c:/mingw-w64_x86_64-mingw/mingw64/bin/../lib/gcc/x86_64-w64-
mingw32/4.4.4/../../
../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lmsvcr90
collect2: ld returned 1 exit status
failure.

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?
Thanks,
