Issue to compile a program with camlp4 in OCaml 3.10.0

[David MENTRE <dmentre@linux-france.org>]

Hello,

I'm trying to compile an OCaml program I haven't written. I'm compiling
it on an Ubuntu 8.04, OCaml 3.10.0.

The compilation fails with following error:
"""
ocamlopt -pp "camlp4o pa_op.cmo" -I src                      -c src/common.ml
File "src/common.ml", line 5, characters 101-102:
Parse error: "in" expected after [binding] (in [expr])
Preprocessor error
"""

Here is the beginning of the relevant file:
"""
(** Common utility functions. *)

(* space *)

let heap_size () : float = float_of_int (Gc.stat ()).Gc.heap_words *. float_of_int (Sys.word_size / 8)  (* in bytes *)

"""

This expression seems correct to me. Is this issue related to one of the
fixes on camlp4 that where made in 3.10.1?

Any idea how to work around this issue (without recompiling latest ocaml
and all the needed libraries)?

Sincerly yours,
david
