Your test function is _not_ an oracle that guards an camlp4
grammar rule. Instead test is kind of a parsing function itself.
Consequently, if parsing succeeds you have to discard some
tokens:

let test rex strm =
  match Stream.peek strm with
    | Some(_,s) when s =~ rex -> 
	prerr_endline "!!!!" ; 
	Stream.junk strm
    | _ -> raise Stream.Failure

   #ocamlfind ocamlc -package str -c -pp "camlp4o -I . pa_extend.cmo q_MLast.cmo " -I /usr/lib/ocaml/3.08.3/camlp4 te.ml
   
I've never used ocamlfind, but why not

ocamlfind ocamlc -package str -c -pp "camlp4o pa_extend.cmo q_MLast.cmo " \
        -I +camlp4 te.ml

(deleted "-I ." and use "-I +camlp4") ?
