---------------------------------------------------------------------------+
 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\convert.hpp(96): error C4127:
 conditional expression is constant if (Close) ...
 }}}
 {{{
 \boost_1_52_0\boost\geometry\algorithms\detail\overlay\get_turns.hpp(263):
 error C4127: conditional expression is constant if
 (InterruptPolicy::enabled) ...
 }}}
 {{{
 \boost_1_52_0\boost\geometry\algorithms\num_points.hpp(51): error C4127:
 conditional expression is constant if (s == open) ...
 }}}
 Maybe it's possible to eliminate those warnings for the next boost
 version?
