MinGW64, openblas, suitesparse, and numpy under windows 64 bit

First of all, I failed.Numpy works only partially. IO crashed it for sure.I did not test it further. But, at least, compiling was fine.

Numpy depends on openblas and suitesparse(umfpack) for performance, suitesparse depends on intel-tbb and metis. I just use pre-built metis for mingw64 on the sourceforge.

Here is my openblas script
make -j4 BINARY=64 CC=x86_64-w64-mingw32-gcc FC=x86_64-w64-mingw32-gfortran NUM_THREADS=2
I used 2 threads due to my i5 cpu.

Here is the intel-tbb script
mingw32-make.exe compiler=gcc arch=intel64 runtime=mingw
install -d ./pkg/usr/local/lib
install -m755 build/windows_*/*.dll* ./pkg/usr/local/lib
install -d ./pkg/usr/local/include
cp -a include/tbb ./pkg/usr/local/include
cd ./pkg
tar cvf tbb_4.1_msys64.tgz ./usr
tar -tf tbb_4.1_msys64.tgz > tbb_4.1_msys64.list

And my suitesparse script
export CFLAGS=" ${CFLAGS} -DNPARTITION"
mingw32-make CFLAGS="${CFLAGS} -fPIC -I/usr/local/include -L/usr/local/lib" METIS="-lmetis" SPQR_CONFIG="-DTIMING -DHAVE_TBB" TBB="-ltbb" BLAS="-lopenblas" LAPACK="-lopenblas" -C SuiteSparse_config/xerbla
