Hello,

Using Boost 1.58 on VC9 (MSVC++ 2008) compiling a small program generates
warnings in the Geometry headers in Release and Debug modes. Please let me
know if this is a Boost.Geometry issue or something I'm not doing correctly.

The program source
=================

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/geometries.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>

typedef boost::geometry::model::d2::point_xy<double> point;
typedef boost::geometry::model::polygon<point,false> polygon;
typedef boost::geometry::model::linestring<point> polyline;

int main()
{
polygon green, blue;
green.outer().push_back(point(-1.0, 1.0));
green.outer().push_back(point(1.0, 1.0));
green.outer().push_back(point(1.0, -1.0));
green.outer().push_back(point(-1.0, -1.0));

blue.outer().push_back(point(0.5, 0.5));
blue.outer().push_back(point(0.5, 1.5));
blue.outer().push_back(point(1.5, 1.5));
blue.outer().push_back(point(1.5, 0.5));

std::vector<polygon> output;
boost::geometry::intersection(blue, green, output);
}
