Comment (by Phyx-):

 Right, so I see the problem...

 You're using the msys version of python, which doesn't correctly search
 for the SO name.

 it doesn't add the ".dll" to it. so the loader doesn't find it. What you
 want, is the mingw-w64 version of python (which is also compiled with GCC
 so MSVC runtime not needed).

 {{{
 pacman -S mingw-w64-$(uname -m)-python3
 }}}

 Odd, the installation of Sphinx should have installed it as well. It would
 be python3.5. The msys python is a bit broken (which is unsurprising, the
 msys versions are usually the bare minimum to get the msys shell itself
 working).

 correct the link from python3 -> mingw python3.5 and you should be good to
 go.
