#3233: serialization problem: enum : __int64
---------------------------------------------+------------------------------

Milestone:  Boost 1.40.0                     |   Component:  serialization
  Version:  Boost 1.39.0                     |    Severity:  Problem      
 Keywords:  __int64 enum serialization       |  
---------------------------------------------+------------------------------
 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?
