Hi Caml list,

I got stuck with calls from ocamlbuild to
  menhir --infer ...
failing because include dirs (-I dir) were not given as parameters.

The fact is that menhir currently does not accept such parameters.
I found a dirty workaround using
  menhir --ocamlc "ocamlc -I dir" ...
but this could override an other --ocamlc parameter.

Looking at menhir and ocamlbuild code, I thought a tiny patch to both
was the best choice:
   - a patch to learn menhir about -I options
   - a patch to ocamlbuild to feed menhir --infer calls with -I options
     (using the same argument generation code as for other commands)

Those patches are attached.

Regards,
Stéphane.
