Well yes, this is windows !

Hmm, 

For starters I reccomend using python's Distutils and then building 
extensions should just happen automagically in a cross-platform way.

If you really want to hand build extensions with Makefiles I suggest
downloading the Cygwin Python source distribution and studying 
how it is done there.  

specifically look at the following make defines

CCSHARED
LDSHARED
BLDSHARED

But learn to use the Distutils module, 
it is MUCH simpler once you get the hang of it :-)

Questions about using Distutils should be asked on the Python List

Cheers

Norman
