 In transform_detail.hpp of boost polygon line 257 you write

 int this_array[3] = {horizontalDir.to_int(),
                          verticalDir.to_int(),
                          proximalDir.to_int()};

 where horizontalDir is a direction_3d defined in isotropy.hpp and the
 to_int() function is defined in line 529 as
 inline unsigned int to_int(void) const { return val_; }

 returning an unsigned int. Using the uniform initialization with {}
 results in narrowing which is imho not allowed in c++11. At least the llvm
 clang 3.1 compiler complains.

 Possible fixes afaik to_int() could return int or array should be defined
 as unsigned int
