If you find out let me know .. since I've spent over 5 years
designing a new programming language primarily to solve this problem.
Had ocaml supported generating shared libraries (dlls) and 
dynamic loading of them, at the native code level, I would
have used Ocaml.

The bottom line is that basically it can 'just work', since
native code is just native code, all you really need is
that the library code link to the right symbols to
provide access to the run time (and of course you need
to initialise it).
