I like your project a lot and adhere 100% to your minimalist views. Using #include in this way is neat and I suspect it may be possible to further this 'brutal' approach with pre-processor tricks and struct permissiveness. To help code legibility you could maybe put the socket functions in a separate file ? Or even make it a lib. (Though I admit it may go against your compactness goal). Same for HTTP stuff.
