As discussed on IRC, there are some win32 incompatibilities in current
Storm trunk due to its lack of support for relocations in static
initialisers (which essentially means you can't declare a global
variable to contain a pointer to a function or variable found in
another DLL).

I've put a branch up for review that fixes those problems
(lp:~jamesh/storm/bug-268151), but you reported the following link
errors on IRC:

20:01 <akm1> jamesh, am getting different

These are symbols that should be provided by the Python DLL.  I'm not
familiar enough with the mingw32 toolchain on Windows to help here
unfortunately.  I don't think these errors indicate errors on the
Storm side though.  If I'm wrong, it'd be nice to know what else needs
changing.
