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 
with 
modules/DLLs (even when they are explicitly loaded/unloaded multiple 
times), but these changes have not yet made it into CVS.

Martin
