As someone said, he is keeping the platform layer and game layer separated, the game layer is meant to be platform independent. The idea is to write in real time every single line of code, and if he had tried to set up multiple platforms from the start he would have spent months in mostly boring and repetitive tasks, while he wanted to get to game programming as soon as possible, and get back to support more platforms later. After the first few weeks setting up the windows code, the focus has been on the game layer mostly. He is using mostly straight C (stating several times that he loathes C++) using a small subset of C++ features (function and operator overloading).
