Hello,

I have been getting compiling errors when using coordinate_matrix. For
example:

#include <boost/numeric/bindings/ublas/matrix_sparse.hpp>
using namespace boost::numeric::ublas;

// File: b.cpp
int main ()
{
    coordinate_matrix<double> A(5, 5, 12);

    A(0, 0) = 2.;
    A(0, 1) = 3;
    A(1, 0) = 3.;
    A(1, 2) = 4.;
    A(1, 4) = 6;
    A(2, 1) = -1.;
    A(2, 2) = -3.;
    A(2, 3) = 2.;
    A(3, 2) = 1.;
    A(4, 1) = 4.;
    A(4, 2) = 2.;
    A(4, 4) = 1.;

    return 0;
}

The errors are:

If I change it to "compressed_matrix" it compiles just fine.

I just updated boost and bindings through svn.

Any ideas?
