Bug description

Full_Name: Jere Sanisalo

OS: WinXP
Submission from: ip213-185-36-33.laajakaista.mtv3.fi (213.185.36.33)

I'm currently developing a native library for OCaml with C++. Everything seems
to compile ok, but in the linking phase it complains about missing ocaml
functions (such as failwith, alloc and alloc_tuple). The problem is, that the
ocaml header files do not specify 'extern "C"' for function declarations under
C++ (they should be defined as 'extern' under C, but this is not done either, as
I see it).

A quick hack is to include the header files like:

extern "C" {
#include <caml/alloc.h>
#include <caml/fail.h>
#include <caml/memory.h>
#include <caml/mlvalues.h>
}

This compiles, links and works as expected (but is a temporary hack
nonetheless).
