I have recently upgraded to Boost 1.46 and am having trouble compiling the following simple program (Using Visual Studio 2005):

// Error.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

#include <tchar.h>

#include <iostream>

#include <boost/property_tree/ptree.hpp>

#include <boost/property_tree/json_parser.hpp>

void Go()

{

      boost::property_tree::ptree t;

      boost::property_tree::read_json(std::cin, t);

}

int _tmain(int argc, _TCHAR* argv[])

{

      Go();

      return 0;

}

Here are the errors I get:
