Pyhon 2.5 doesn't support VS 2008. It has unofficial support for VS 2005
in the PCbuild8 directory. You can mail Martin von Löwis and ask him for
a debug build of Python 2.5.2. I don't have the tools on my build box.

A debug build changes large parts of the ABI. Every PyObject struct
gains additional fields, lots of checks are added to Python's memory
allocation system and asserts are enabled. Debug extensions have a _d
suffix for a very good reason. We aren't just trying to make *your* life
