The easiest way to force the inclusion of a particular .o(bj) file is to 
call a function from it. You could call a function from each .cpp file in 
which you have an export macro.

This is in fact not much different than just having "register<X>()" calls 
instead of export macros, which is why I tend to prefer this low-tech 
approach instead of relying on implicit registration via static object 
constructors.

Maybe the serialization library could provide an alternative function-based 
registration mechanism that would be immune to the static library problem. 
Or maybe it already provides it:

    guid_initializer< T >().export_guid( "T" );

This is less convenient, but has the advantage of working. :-)
