Re: Ocamlfind does not allow -thread

Hello, I'm back with this problem and some new tests :

- I've switch back to ocaml system.
- Renamed « ~/.opam/4.02.1 » and removed this entry in « ~/.opam/aliases 
»
- did « opam switch 4.02.1;opam install ocamlfind »

And I reproduced the same error :

$ grep type_of_threads /home/dailly/.opam/4.02.1/lib/threads/META
/home/dailly/.opam/4.02.1/lib/threads/META:type_of_threads = "vm"

(which was fine before I recompile this version)

This does not seems related to the ocaml version, but rather a change in 
the environnement (cygwin update ?)

Is there a way to check this just after the ocaml compilation ? I'll try 
to compile ocaml from source outside opam and check the compilation 
result.

Thanks
