Your C++ compiler has to match the C++ compiler used to compile Python -
which, I think, by default, on Vista is Visual Studio 2008.

However, the weave module is not actively maintained, and there are much
better options right now for interfacing with C/C++.  I would highly
suggest that if you have some performance-critical part of your code, you
either use Cython, or, if it is a simple numerical expression, use the
amazing numexpr package.

I warn you though - while pure Python code is very portable across
platforms, interfacing Python with other libraries (mostly, C and C++) is a
huge pain on Windows.  If you really want to continue, I strongly advise
you take advantage of Christoph Gohlke's work:

http://www.lfd.uci.edu/~gohlke/pythonlibs/

who has done all the hard work has made binary installers for most of the
hard-to-compile Python libraries with C and C++ dependencies.
