-----------------------------------------------------------------------------------------+
 I'm using Microsoft Visual Studio 2012 to compile boost 1.52.0. I use
 compiler flag /W4. The following warnings (which we declared errors for
 our project) occur in geometry, regardless whether I'm compiling for x64
 or x86:
 {{{
 \boost_1_52_0\boost\geometry\algorithms\detail\overlay\get_turns.hpp(140):
 error C4189: 'n' : local variable is initialized but not referenced
 int const n = int(section.range_count);
 }}}
 {{{
 \boost_1_52_0\boost\geometry\strategies\cartesian\distance_projected_point.hpp(161):
 error C4189: 'fp_strategy' : local variable is initialized but not
 referenced
 fp_strategy_type fp_strategy
             = strategy::distance::services::get_similar
                 <
                     Strategy, Point, fp_point_type
                 >::apply(strategy);
 }}}
 Maybe it's possible to eliminate these warnings for the next boost
 version?
