That sounds like a big headache for OCaml: native code generated by
OCaml are bundled together at link-time. For instance, in Liquidsoap,
where ocaml-soundtouch is used, we use C and C++ code for the
bindings.
Therefore, there is no reason to use g++ to link the final binary...
Do you have any idea concerning this situation?
