[C++-sig] boost.python: tss_cleanup_implemented link error windows 64 bit

Boost python is being compiled in .obj files and then the whole lot is 
linked into a .pyd.

Do you have some unit tests we could use to check our builds for 
problems? I've not understood how the dll linking requirement works. 
Where should the dll live and how do you then cope with other people's 
boost based modules, which might link to a different boost dll version?

Many thanks for your help!
