Ocamljitrun is a plugin replacement for ocamlrun (and libcamlrun.a,
renamed as libcamljitrun.a) - it executes Ocaml bytecode (by
translating them transparently into native code). It works with
dynamically linked ocaml modules and toplevels.

So your interpreter might generate Ocaml bytecode (perhaps reusing the
"lambda" representation of Ocamlc) - and ocamljitrun will, when
interpreting it, translate the bytecode to machine code.

Ocamljitrun requires latest Ocaml CVS or future Ocaml 3.08. (the
current 3.07 release won't work with it).

Feel free to ask me additional questions about it.

As I told in my previous posting, you might have a look into MetaOcaml
(see http://metaocaml.org/ for more)
