Optimisation of division in gcc

Question

Here\'s some code (full program follows later in the question):

template 
T fizzbuzz(T n) {
    T count(0);
    #if CONST
        const T d

I'm guessing its just the severely old GCC version you are running. The oldest compiler I have on my machine - gcc-4.1.2, performs the fast way with both the non-const and the wrap versions (and does so at only -O1).
