Moving to 1.55b1 from 1.54 gives:
Error 1 error C2976:
'boost::geometry::strategy::transform::translate_transformer' : too few
template arguments
offending line is:
typedef strategy::transform::translate_transformer<Point, Point>
Translate;
Compilation of what test case/example of Boost.Geometry
using what compiler causes this error?
