I suppose os.path.exists doesnt work as expected on Windows since python is definitely in the path (otherwise it wouldn't even get there...) and that warning was always printed. Also that warning is displayed only when calling em++ and if it was an actual problem it should appear with all the tools (emcc, etc.).
