Note that the only reason for using __declspec on tis platform is that without it, programs compiled in release mode will optimize away code not explicitly referred to. This breaks serialization of derived pointers. So this is a hack to work around over-zealous compiler optimizaton. This has been learned through painful and time consuming experience. It is possible this solution is overkill in some cases, but there is no way to know without investing a lot more effort.
If you have the time, could you explain to me exactly what the problem is (or show me a program highlighting the problem)? How can the code be needed for serialization if it isn't actually "used" from the compiler's point of view? A quite common problem when dealing with factories and such things. 'Niftycounters' can be used to counter this, i.e. forcing code in a cpp to be referenced by including it's header.
How this applies to serialization is a matter unbeknowns to me though. :) /Marcus
