[boost] boost::serialization - problem move to 1.33.1 version

11 Mar 2006

      Hello all !

 I  write small test program using boost::serialization.
If I use boost  1.32 - compilation OK. But I change boost to 1.33.1 -
compiler rise error :(

Where I be mistaken ?

Compiler messages:

OtherTest.cpp
