我从warning C4503移到CGAL 4.4后，我的代码开始生成CGAL 4.12-beta 2。我在Windows 7操作系统上使用Visual Studio 2012。
根据编译器，以下声明是有问题的代码。
struct pairA
{
int A1;
int A2;
pairA():A1(int()),A2(int()){}
};
struct pairB
{
int B1;
IdType B2;
pairB():B1(int()),B2(IdType()){}
};
struct pairInfo
{
pairA pA;
pairB pB;
};
typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;
typedef CGAL::Triangulation_vertex_base_with_info_2<pairInfo, Kernel > Vertex_base; //<0 - boundary , -1 not associated, >0 associated with edge>
typedef CGAL::Delaunay_mesh_face_base_2< Kernel > Face_base;
//typedef CGAL::Triangulation_face_base_with_info_2<std::pair<int,int>, Kernel> Face_base; //does not work with constrained triangulation?
typedef CGAL::Exact_predicates_tag Itag;
typedef CGAL::Triangulation_data_structure_2< Vertex_base, Face_base > Triangulation_data;
typedef CGAL::Constrained_Delaunay_triangulation_2< Kernel, Triangulation_data, Itag > CDTriangulation;
typedef CGAL::Constrained_triangulation_plus_2<CDTriangulation> CDTriangulationPlus;
typedef CGAL::Delaunay_mesh_size_criteria_2< CDTriangulationPlus > Criteria;
typedef CGAL::Delaunay_mesher_2< CDTriangulationPlus, Criteria > Mesher_Base;
typedef CDTriangulationPlus::Vertex_handle Vertex_handle;
typedef std::vector< Vertex_handle > Vertex_handles;
typedef CDTriangulationPlus::Face_handle Face_handle;
typedef CDTriangulationPlus::Point Point;
typedef CGAL::Polygon_2<Kernel> Polygon2D;
我根据网络上的建议定义了pairInof而不是嵌套std::pair，但这似乎并没有消除这个问题。

有没有办法通过更正代码来消除此警告？
