So it does on mine. Many thanks for this fast reply! May I suggest that the 
examples of 3D skin surface meshing in the documentation be fixed also (they 
use the inexact constructions kernel, see 49.5.1 and 49.5.2 at 
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Skin_surface_3/Chapter_main.html)?

Also, after reading the FAQ you pointed to and looking up the relevant 
headers, I concluded that Exact_predicates_exact_constructions_kernel uses a 
lazy kernel by default (which suits me fine, of course), unless 
CGAL_DONT_USE_LAZY_KERNEL is defined before including headers. Is that 
assessment correct? Or is there more to it?

Many thanks again,
FX Coudert
