Try casting it to an LPCTSTR.  That should actually be far enough for  
the Serializer to work, as that is const pointer to a TChar array, and  
TChar is simply a wchar_t or char depending on if you have Unicode  
turned on.  I wouldn't put any bets on the serialized data loading  
into another app that was compiled with the opposite Unicode setting.

ar & (LPCTSTR)(m_3rdPartyClass.m_SomeCString);
