[Boost-users] uBLAS with MS vc 7.1

I wrote a simple program using uBLAS under vc 7.1, but
got so many warnings, how can I correct it?

The code is:
----------------------
#include <boost/numeric/ublas/matrix.hpp>

namespace ublas = boost::numeric::ublas;

int main(int argc, _TCHAR* argv[])
{
    ublas::identity_matrix<double> A(4);
    ublas::identity_matrix<double> B(4);

    prod(A, B);
        return 0;
}
------------------
But I got the following warning:
d:\Project\Libraries\boost_1_32_0\boost\numeric\ublas\traits.hpp(941)
: warning C4267: 'argument' : conversion from 'size_t'
to 'const unsigned int', possible loss of data

Y=boost::numeric::ublas::identity_matrix<double>::size_type
        ]
        d:\test\boosttest\boosttest\boosttest.cpp(14)

        ]

        ]

How to correct it? thank you very much:)
