Thomas Réfis and Jérémie Dimino have been working on ocamlnat in trunk
recently, and ocamlnat builds on either the "trunk" branch or, I believe,
the 4.03 release. You should talk to them.

Let me take this an opportunity to advertise the "runtop" target in the
compiler distribution's Makefile, which runs a toplevel from an
(uninstalled) build of the compiler distribution:

  make runtop
  make natruntop

I added them during the 4.03+dev release cycle, but didn't mention it in
the Changelog (they're not user-facing features) so most people keep doing
weird incantations of (./byterun/ocamlrun ./ocaml -I nostdlib ...) instead.
