Can't compile rtree.remove in 1.56 and 1.57 (1.55 works fine)

See attached file. It can be compiled with boost 1.55 but not in 1.56 and 1.57.

testcase

The problem was located in the default bgi::equal_to<> function object. As a workaround a user-defined one could be passed to the rtree:

typedef std::pair<GeometryBox, GeometryPolygon * > Value;

struct equal_to
{
    bool operator()(Value const& v1, Value const& v2) const
    {
        return boost::geometry::equals(v1.first, v2.first)
            && v1.second == v2.second;
    }
};

boost::geometry::index::rtree
    <
      Value,
      boost::geometry::index::linear<16>,
      boost::geometry::index::indexable<Value>,
      equal_to
    > rtree;
