The most important thing is to make sure your MAKE string contains "PTR64=0" and that you have an environment variable created "CONFIG_ARCHITECTURE=x86". Presumably the preset batch files are supposed to do this for you to allow 32-bit compile on 64-bit systems. The prompt you see should show [MINGW32] for 32-bit and [MINGW64] for 64-bit.
