That's a nice idea.

I've set up a small .def file which contains all the symbols that I
want to import from the main.exe and use inside the DLL:

;main.def
LIBRARY _main.dll
IMPORTS
  a_func = main.exe.a_func
  b_func = main.exe.b_func

Then I build the DLL like this:

gcc -shared -o _main.dll main.def file1.o file2.o ...

The DLL builds fine then. But when I (or rather the Python interpreter)
want to load the DLL, then the following error message is raised:

   DLL load failed with error code 193

What does this mean? Did I misunderstand anything?
