Hello,

I am attempting to use snap rounding with a custom kernel ( new point
container ).
I am basing the test code on the CGAL Kernel23/ example.

I am seeing gcc errors, and I suppose I need some more glue, but am unable
to tell what that may be.

Any direction in how to proceed would be appreciated.

I've created a gist with the gcc error log, and sample code on github here:
https://gist.github.com/petersadro/0d6a80764752869d8639c3d6bf82e7d1

I have no idea where this is documented, but cgal kernel functors use the boost/tr1 result_of protocol, and at least the error message is very clear. You are missing:
typedef const FT* result_type;
in class MyConstruct_coord_iterator.

Kd_tree_rectangle.h seems to have a bug, it should not use Construct_cartesian_const_iterator_d::result_type directly but go through result_of instead. This would make the typedef unnecessary in C++11.
