That dance is primarily to set your system up to allow compiling *any* 
distutils-based C extension (assuming it's usable on Windows), without 
having to do any manual steps.

Probably, to all of the above.  Of course, you have to perform those steps 
manually.  Doing the "full dance" allows the above to be done with a short 
'setup.py' file that doesn't need to know anything about the specific paths 
involved.
