The code as posted looks solid to me.

This might be trivial, but

Checked that the code is actually included in the place where the
serialization is instatiated ?

Have you tried replacing your typedefs with __int64 ? (thus removing the
typedefs)

Or maybe use the STRONG_TYPEDEF macro that comes with serialization lib
(undocumented i think).
