// BSG 2012-02-06: we use this currently only for distance.
// For other scalar results area,length,perimeter it is commented on purpose.
// Reason is that for distance there is no other choice. distance of two
// empty geometries (or one empty) should NOT return any value.
// But for area it is no problem to be 0.
// Suppose: area(intersection(a,b)). We (probably) don't want a throw there...

// So decided that at least for Boost 1.49 this is commented for
// scalar results, except distance.
