[Boost-users] Visual C++ 2003 and Boost 1.35

Hello!

I'm having a problem with using Boost 1.35 on Visual C++ 2003 SP1. Take a
look at the following very simple program:

------------------------------------
#include "stdafx.h"
#include <boost/interprocess/sync/interprocess_upgradable_mutex.hpp>
int _tmain(int argc, _TCHAR* argv[]) {	
        int i = 0;
        unsigned int j = 2;
        j < i;
        return 0;
}
------------------------------------

It does nothing, just emits a compiler warning. Unfortunately, this warning
is followed by lots of meaningless messages related to the included Boost
header:

------------------------------------
BoostTest2.cpp
c:\BoostTest2\BoostTest2.cpp(11) : warning C4018: '<' : signed/unsigned
mismatch
        c:\Program
Files\boost\boost_1_35_0\boost\interprocess\sync\interprocess_upgradable_mut
ex.hpp(621) : see reference to class template instantiation
'boost::interprocess::upgradable_lock<M>' being compiled
        with
        [
            M=boost::interprocess::interprocess_mutex
        ]
        c:\Program
Files\boost\boost_1_35_0\boost\interprocess\sync\interprocess_upgradable_mut
ex.hpp(621) : see reference to class template instantiation
'boost::interprocess::upgradable_lock<M>' being compiled
        with
        [
            M=boost::interprocess::interprocess_mutex
        ]
------------------------------------

If I remove #include <boost..., the extra messages go away. It looks to me
like compiler bug. The exe produced is probably ok, but the amount of spam
in output window makes using Boost very cumbersome. Is there any way to make
these messages go away?
