Hi,

I have a funny when building the SWIG wrapper on Win32 using the
straightforward 'python setup.py build':

The compile step goes well. When linking it gets a bunch (15) of unresolved
externals:

unresolved externals

If I then go and execute exactly the same link command (copy and pasted from
the shell into a .bat file), these unresolved externals mysteriously
dissapear and the .pyd is fully usable!

Any help appreciated!
