Ah, now I see! I've checked for a def file, but I forgot about the
linker options. I was always using the distutils and indeed, there's a
"/EXPORT:initxtest" given to the linker. Thanks for clearing that one
up.

For the sake of understanding, I tried to use this macro, but it takes
an argument. What's that argument supposed to be?
I had a look in the Python source and also read about the macro
USE_DL_EXPORT. Do I have to define that myself before including
Python.h (but DL_EXPORT was defined even without defining
USE_DL_EXPORT myself)? Well, whatever I tried, I didn't really manage
to compile the module that way....
