Or even more conveniently: check out the current CVS-repository at INRIA!
Seems that the problems with integers are soon going to be history...

  -> ocaml/stdlib/int32.mli
     ocaml/stdlib/int64.mli

Though, I fear that unboxed, complete native integers will never be
supported. Anyway, if you only need complete 32-bit-ints, you may as well
purchase a real processor (Alpha)... ;-)
