Hi,

When using precompiled headers,  BOOST_TYPEOF_REGISTER_TYPE() macro throw some erros.

stdafx.h:

---
#pragma once
#ifndef _WIN32_WINNT        // Allow use of features specific to Windows XP or later.                   
#define _WIN32_WINNT 0x0501    // Change this to the appropriate value to target other versions of Windows.
#endif                        
#include <boost/typeof/typeof.hpp>
---
test_boost_auto.cpp :
---
#include "stdafx.h"  // 1
//#include <boost/typeof/typeof.hpp>  // 2
#include BOOST_TYPEOF_INCREMENT_REGISTRATION_GROUP()
class A
{
};
BOOST_TYPEOF_REGISTER_TYPE(A)
int main()
{
    return 0;
}
---
When "USE precompiled headers" is turned on, the above code return this error when compiled:
---

When I turn off precompiled headers, comment 
#include "stdafx.h"
and uncomment
//#include <boost/typeof/typeof.hpp>  // 2
everythings compile fine.
thanks
