Although 4.8 is listed as a supported platform, I discovered that due to a
bug in gcc it is unsafe to use cgal with g++ 4.8.1: everything compiles but
you get random segfaults when building AABB trees.

I switched to g++ 4.7 which resolved the issue.

While I fully understand this is the fault of GCC, and not CGAL, many users
on Ubuntu 13.10 will have 4.8.1 installed as their default compiler. Please
consider adding a note on the CGAL web site or install documentation so that
they may avoid this pitfall.

Best,
Etienne
