Hi all,

I am linking against CGAL3.5 and trying to compile the example code from this 
page: 
http://www.cgal.org/Manual/last/doc_html/cgal_manual/Surface_reconstruction_points_3/Chapter_main.html#Subsection_45.3.2

However gcc4.2.1 spits out the following errors:
/Users/ekurutepe/Dropbox/Development/depthRender/depthRender/../../lib/include/CGAL/Meshes/Triangulation_mesher_level_traits_3.h:76:0

The call causing this error is:

    STr tr; // 3D Delaunay triangulation for surface mesh generation
    C2t3 c2t3(tr); // 2D complex in 3D Delaunay triangulation
    CGAL::make_surface_mesh(c2t3,                                 // 
reconstructed mesh
                            surface,                              // implicit 
surface
                            criteria,                             // meshing 
criteria
                            CGAL::Manifold_with_boundary_tag());  // require 
manifold mesh

When I dug a little deeper into the source code I found out that C2t3 is a 
typedef for Complex_2_in_triangulation_3 and that 
Complex_2_in_triangulation_3 indeed does not have the Locate_type and 
Weighted_tag types. On the other hand Locate_type and Weighted_tag are types 
in Triangulation_3 which is NOT a parent class of 
Complex_2_in_triangulation_3.

Is this an error on my side or did maybe a recent commit break the example 
code? 

Thanks a lot in advance.

Cheers,
