Missing build instructions for Windows

As I want to fix fullscreen issue on Windows,

I've tried to build Ivan with Visual Studio 2015 but it refuse to use them
I've also tried to use cygwin but met lot of issues with autoconf / automake

Can you give me tips to build Ivan for Windows ?
It should great to fill wiki (on github or here) with these instructions

I use a modern distribution of MinGW 32-bit. I also store my SDL 2.0.4 distro inside the MinGW file system - which is really bad practice, so you will want to edit the makefile to point the SDL 2.0 in a separate folder.
If your IVAN code is in say

C:\ivan

You can use the following command:

C:\MinGW\bin\mingw32-make.exe -f C:\ivan\makefile.mak

On this makefile:

# Iter Vehemens ad Necem makefile for MinGW environment

To compile IVAN for windows.

Let me know if this helped by the way.
