Well... the settings can be tricky.  Fortunately there is
an easy way to do this.

Save this code into a file named "setup.py" in the same directory
as "_grabscreen.c" and "ImageGrab.py".

# ------------------------------------------------------------
""" Setup script for grabscreen """
from distutils.core import setup, Extension

setup(name = "grabscreen",
      ext_modules = [Extension("_grabscreen",
                               sources = ["_grabscreen.c"],
                               libraries = ["gdi32"])],
      py_modules = ["ImageGrab"])
# ------------------------------------------------------------

Then do:
  python setup.py build
This builds everything, probably under .\build\lib.win32-2.2 .
On my computer, the resulting PYD file is 20K bytes.

If you decide to install it, you can:
  python setup.py install
