[Caml-list] embedding OCaml into C on win32

["Alexander V.Voinov" <avv@quasar.ipa.nw.ru>]

Hi 

I have a small program, similar to one in the manual (where
fib_closure is defined). I try it on win32, with VC 6 and
ocaml-3.04.

The Makefile and the source texts are as follows. What else should I
add to the link command to resolve these externals?

Thank you

Alexander
