This release should now compile with g++-4.0 as well. The 'name' handling has been changed fairly rigorously and should work much better now.
Overhaul of the evaluation engine makes for much speedier execution + cleaner code.
Forgot to remove a dependency on the boost library. Apologies
Push-3.0.2 is a new version where the example file 'pushgp_int' has been simplified. It also no longer depends on the boost library.
