Hi Ben,

It works, but (if I recall) it uses some O(n^2) algorithms that makes it
unbearably slow for large programs.

If it works, but is slow, then I think that we should leave it in. It is not harming anyone at the moment, and anyone who does complain about it can be redirected to gcov and a modern gcc.

Cheers
  Nick
