10531	Upgrade to boost 1.56.0 breaks compilation of boost::polygon code	fiesh@…	Andrii Sydorchuk	"The following code compiled until 1.55.0.  It stopped doing so from 1.56.0 on.  I didn't mark the component as boost::polygon since it appears it wasn't changed and might be a problem related to something else.

{{{
#include <vector>
#include <boost/polygon/polygon.hpp>
int main()
{
	typedef boost::polygon::polygon_data<int> Polygon;
	typedef boost::polygon::polygon_set_data<int> PolygonSet;
	PolygonSet ps;
	std::vector<Polygon> output;
	ps.get(output);
}
}}}

My output (with gcc 4.8.3) is:
