Build error gcc (GCC) 6.1.1 20160501

[heshamsafi]

Hello,

first of all, this is a great compilation of non-trivial algorithms ... thank you for putting it together.

secondly, I get this build error for suffix_tree in my environment.
most probably compiler dependent issues.
I will look into it and if i fix it I will send a pull request from a fork.
