There is indeed an incompatibility between the code of CGAL-4.5 and TBB-4.3.

If you look at the error messages more deeply, you can see that in both cases 
the error is triggered by <CGAL/Spatial_lock_grid_3.h>, line 629:

/usr/local/include/CGAL/Spatial_lock_grid_3.h:629:12: note: in instantiation 
of member function 'std::__1::vector<tbb::recursive_mutex, 
std::__1::allocator<tbb::recursive_mutex> >::resize' requested here
m_grid.resize(num_cells);
^
/usr/local/include/tbb/recursive_mutex.h:39:25: note: copy constructor of 
'recursive_mutex' is implicitly deleted because base class 
'internal::mutex_copy_deprecated_and_disabled' has a deleted copy constructor
class recursive_mutex : internal::mutex_copy_deprecated_and_disabled {
^
/usr/local/include/tbb/tbb_stddef.h:334:44: note: copy constructor of 
'mutex_copy_deprecated_and_disabled' is implicitly deleted because base class 
'tbb::internal::no_copy' has an inaccessible copy constructor
class mutex_copy_deprecated_and_disabled : no_copy {};



With TBB-4.3, can you please try to erase, or comment out, the following 
specialization:

  template <>
  class Spatial_lock_grid_3<Tag_non_blocking_with_mutexes>

between lines 614 and 665 of <CGAL/Spatial_lock_grid_3.h>? That 
specialization is actusally not used by CGAL, and it should fix the 
compilation errors with TBB-4.3.
