Subject: Fail on deprecated warning even for Ocaml > 4.02.3

Deprecations which can't be fixed in 4.02.3 are locally wrapped with
[@@@ocaml.warning "-3"]. The only ones encountered are
- capitalize to capitalize_ascii and variants. Changing to ascii would
  break coqdoc -latin1 and maybe other things though.
- external "noalloc" to external [@@noalloc]
