That's wrong. Should be:

DL_EXPORT(void)
inititemlist(void)

DL_EXPORT is a Python macro that will do the symbol exporting trick on any
platform you might wish to compile your project.

Btw. I recommend you follow Alex's advice to use distutils. It really makes
your job much simpler. I always found it confusing which runtime libraries to
link against in MSVC, how to import/export symbols, etc.
