Hello,

there's a problem building ocamlnet 3.6 with OCaml 4.0 (related to some
changes to inference of optional parameters):

ocamlfind ocamlc -g  -I ../../src/netstring -package "unix camlzip"  -c
netgzip.ml
File "netgzip.ml", line 326, characters 13-33:
Error: This expression has type ?level:int -> unit -> deflating_pipe
       but an expression was expected of type
         unit -> Netchannels.io_obj_channel
make[1]: *** [netgzip.cmo] Error 2
make: *** [all] Error 2

The workaround is to edit src/netzip/netgzip.ml so that line 326 passes an
explicit ``level'' option to deflating_pipe:

let () =
  Netcompression.register
    ~iana_name:"gzip"
    ~decoder:(new inflating_pipe)
    ~encoder:(new deflating_pipe ~level:6)
    ()

Regards,
Matías.
