Hi again,

I have created a myocamlbuild.ml which fixes the issue but I'm still
interested to get your advice.

open Ocamlbuild_plugin
open Command

let _ = dispatch begin function
   | After_rules ->
       flag ["ocaml"; "thread"; "compile"]  (S[A "-thread"]);
       flag ["ocaml"; "thread"; "link"]     (S[A "-thread"]);
   | _ -> ()
end

Rémi
