I may be missing something, but... doesn't the embed.c demo/example,
D:\Python-2.1\Demo\embed\demo.c on a typical Python install on Win32
for ex., do exactly what you require...?  Well, almost -- it doesn't
actually run any useful Python code, just leave a space where you
could insert your own:-).  But it does show the embedding C program
adding a module, called "xyzzy", which exposes to Python a C function,
called "foo" (from the Python side of things).  Your Python code
invoked from demo.c could "import xyzzy" and then call xyzzy.foo().

So, WHAT am I missing...?
