Look at the documentation of the function
CGAL::create_interior_straight_skeleton_2 [1]. The third parameter of
the overload used in the example lets you specify the kernel that is to
be used for the return Straight_skeleton.

It's a little bit odd that the parameter is not chosen depending on the
input primitives, but has to be manually specified.

Also, you are linking to the CGAL 4.0 documentation. Be careful to use
the right documentation for the version you are using.

HTH,
Philipp
