Is there a reason you're producing C code here?  I've had good results 
just doing:

1) Use ocamlopt -c on ocaml files to produce .cm[oi] files (note: no 
-output-obj here).
2) Use gcc -c on C files to produce .o files
3) Use ocamlopt to link .cmo and .o files.

It looks like you might need to link in some Ocaml-specific libraries.
