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?

It definitely won't if you use dllexport, but there shouldn't be any
reason why it can't work apart from that.
