Getting rust to build on windows can be a bit annoying in setting up all the toolchains and whatnot. The whole process is made much easier by using msys2 so let's document that prominently right on the README.

### Building on Windows
To easily build on windows we can use [MSYS2](http://sourceforge.net/projects/msys2/):
1. Grab the latest MSYS2 installer and go through the installer.
2. Now from the MSYS2 terminal we want to install the mingw64 toolchain and the other
tools we need.
$ pacman -S mingw-w64-i686-toolchain
$ pacman -S base-devel
3. With that now start `mingw32_shell.bat` from where you installed MSYS2 (i.e. `C:\msys`).
4. From there just navigate to where you have Rust's source code, configure and build it:
$ ./configure --build=i686-pc-mingw32
$ make && make install
