here's another iteration: the top of that page says:

    "There are two approaches to building extension modules on Windows,
    just as there are on Unix: use the distutils package to control the
    build process, or do things manually. The distutils approach works
    well for most extensions; documentation on using distutils to
    build and package extension modules is available in "Distributing
    Python Modules". This section describes the manual approach to
    building Python extensions written in C or C++. "

if you're not 100% sure what you're doing, and why you need to use the
manual approach (you don't), *please* use the distutils solution. here's
a minimal setup script:

from distutils.core import setup, Extension

setup(
    name="mymodule",
    ext_modules = [Extension("mymodule", ["mymodule.c"])]
    )

to build, use "python setup.py build". to build a local copy ("in place"), use
"python setup.py build_ext -i". to build and install, use "python setup.py
install".

no need to download any extra stuff; it just works.
