3233	serialization problem: enum : __int64	dcb_BanDos <ban_dos@…>	Robert Ramey	"I have a enum and structure:
{{{
#!c
typedef enum : unsigned __int64 {
    epUnknown = 0x0,
        epCpuSystem =    0x0001LL,
....
         epAvgCpu=    0x100000000LL
}  CGenericParamParam;

struct fee
{
....
 CGenericParamParam param;
}
}}}
Then i try to serialize this structure into boost::archive::binary_oarchive via boost::serialization:

{{{
#!c
template<class Archive, class T>
struct save_enum_type
{
    static void invoke(Archive &ar, const T &t){
        // convert enum to integers on save
        const int i = static_cast<int>(t);
        ar << boost::serialization::make_nvp(NULL, i);
    }
};
}}}
Casting __0x100000000LL
 into int gives 0.
Any ideas?
