Unfortunately, simply building boost::serialization as DLL under
Windows is not enough because the extended RTTI objects for a class
are duplicated in each module/DLL. This is because the static extended
type info instances are defined in header files, and under Windows
this will cause an instance to be created for each module that
includes that header file.

This effectively means that serializing a class defined in one DLL
from another DLL will not work properly. I've made some changes to
boost::serialization that allow DLL builds and allow using the library
modules/DLLs (even when they are explicitly loaded/unloaded multiple
times), but these changes have not yet made it into CVS.
