[Caml-list] Stream parser in 3.03alpha ... ? <-> ??

[Christophe Raffalli <Christophe.Raffalli@univ-savoie.fr>]

I just noticed something is missing in the Upgrading file for ocaml-3.03:

II Non-label changes

Q2: I get a syntax error when I try to compile a program using stream
    parsers.

A2: Stream parser now require camlp4. It is included in the
    distribution, and you just need to use "ocamlc -pp camlp4o" in
    place of "ocamlc".

Q2': I still get a syntax error when I try to compile a program using stream
    parsers.

A2': Hops, we did come back to a single question mark (? instead of ??) for
    error management in stream parser.

So the story is 
  ocaml < 2.99 =          a single question mark
  ocaml >= 2.99 < 3.03    two question marks
  ocaml >= 3.03           a single question mark

PLEASE stay with two question marks because maintening OCaml software so that
they compile with many versions will become a nightmare soon :-(
