[Boost-users] warnings with boost::bind

Hello,

I have a question. I use boost::bind with the following class:

class B
{
        int data;
}

class A
{
        bool SetData(const B&){return true;};
}

now when I make somewhere the following:

A a;
boost::bind<bool>(&A::SetData,&a);

I get a warning

8>D:\boost\boost_1_34_1\boost/bind.hpp(1575) : warning C4180: qualifier 
applied to function type has no meaning; ignored
8>        D:\boost\boost_1_34_1\boost/bind.hpp(1609) : see reference to 
class template instantiation 'boost::_bi::add_cref<Pm,I>' being compiled
8>        with
8>        [

Microtec::TrackingInfo &),
8>            I=1
8>        ]
8>        .\Program.cpp(2385) : see reference to class template

Microtec::TrackingInfo &),
8>            A1=bool
8>        ]

I think it is for the const reference. Is this a problem? Is there some 
way to avoid it (okay the way with pragma I know)?

I use boost 1.34.1 and MSVC2005
