ocamlopt and linking

[Taras <taras.judge@shaw.ca>]

Hi,
I'm trying to link an ocamlopt-generated object file into a C program by 
following instructions on http://caml.inria.fr/ocaml/htmlman/manual032.html

Here is a small testcase: http://glek.net/~taras/os.tar.bz2

Currently it seems that main is already defined in libasmrun and some 
symbols are missing from it.

cc -L /usr/lib/ocaml -lasmrun -ldl -lm -lcurses -o prog modwrap.o 
mod_from_ml.o main.c
