Well, when programming in caml, I use the following rules (which I hope to be

+ ocamlc does perform tail call elimation
+ ocamlopt does it less often. Namely, calls in tail position
  become real tail calls when all their arguments are passed in registers.
  (This does not apply to self-tail calls which are always optimized)

  On pentiums/x86/IA32 this means that tail calls are performed when the callee
  has four arguments or less (if I remember well).
