You should really use CMake to build on mingw:
> cmake path/to/llvm/source -G"MinGW Makefiles"
Note that you'll need "mingw32-make.exe" installed in the mingw/bin folder.
Alternatively, install MSYS and run CMake from the msys bash shell:
> cmake path/to/llvm/source -G"MSYS Makefiles"
It might be possible to do (from MSYS):
But it surely will be slower than running CMake.
Hope this helps!
