The trick is the usage of MinGW compiler + 'make' from MSYS (which is
similar to cygwin but play much better with MinGW).

Doing this way, we have ./configure, make and make install that mimics
*nix system while compile native versions, thus the compilation of the
extensions is performed flawlessly.

Switch to mingw-make break this since the generated Makefile by
configure contains *nix PATHs, which are not compatible with
mingw-make.
