[Ocaml-lib-devel] compilation issues

[Pietro A. <Pie...@an...>]

Hi all,
I want to distribute extlib with my project and to do so I added a
Makefile to it. When compiling it on debian unstable (ocaml 3.07)
everything it's ok. When I try to compile the same code, with the same
makefile and ocaml 3.06 (debian woody) I get a complain about extString:

[...]
ocamlc -c extString.mli
ocamlc -c extString.ml
The implementation extString.ml does not match the interface extString.cmi:
Modules do not match:
  sig
    exception Invalid_string
    external length : string -> int = "%string_length"
    external get : string -> int -> char = "%string_safe_get"
    external set : string -> int -> char -> unit = "%string_safe_set"
    external create : int -> string = "create_string"
    val make : int -> char -> string
    val copy : string -> string

[...]

    val lowercase : string -> string
    val capitalize : string -> string
    val uncapitalize : string -> string
    type t = string
    val compare : t -> t -> int
  end
The field `compare' is required but not provided
The field `t' is required but not provided
make[1]: *** [extString.cmo] Error 2
#> 

my naive solution was to add
type t = string
let compare = compare in the extString.ml file.

now it compiles with ocmal 3.06, but it complains with 3.07 because 
there's a dup definition...

is it a known problem ? attached there's the makefile (using
OCamlMakefile) and the META file that might be useful having in the
extlib distribution...
