I've cloned your branch, but hit a snag. First, handle_tangencies.hpp
needed a little change. I removed this line:

#include <boost/geometry/policies/robustness/rescale.hpp>

as in your last commit you split that file into three other files, which
are (indirectly) included anyway on the next line, as it includes
Now I get this error:

robustness/zoom_to_robust.hpp(425): error C2338: boost::is_same < typename
geometry::tag<Point>::type, geometry::point_tag >::type::value
robustness/zoom_to_robust.hpp(433) : see reference to class template
instantiation 'boost::geometry::rescale_policy_type<Point>' being compiled

I get this error as soon as I #include something from Boost::Geometry; my
test code consisted of the single line:

#include <boost/geometry/algorithms/union.hpp>

To make sure I'm using the code in your branch, I've renamed my
.../dependencies/boost_1_55_0/boost/geometry directory to
"geometry-moved-out-of-the-way", and added your branch at
"c:/workspace/geometry/include" to the include file search paths.

Thanks for any help you can give me.

PS: I see you live in Amsterdam, so do I, so perhaps there are easier ways
to communicate than this list ;-)
