libmsi.a import library from wine, and header files available (entirely free software), available for python-win32 builds under msys+wine

as part of building python2.5.2 under msys under wine on linux using mingw, i thought i'd try building _msi.pyd just for kicks. of course, that required having an msi.lib import library, and associated header files. so, purely as an experiment, i've documented the process by which it is possible
