It seems not to work – at least with ocaml 3.10.2 from godi.

 I have:

>> ocamlbuild -show-tags mtsvrac.oocamlfind
>> Tags for "mtsvrac.oocamlfind":
>> {. dont_link_with, extension:oocamlfind, file:mtsvrac.oocamlfind, quiet,

>> Finished, 0 targets (0 cached) in 00:00:00.

and still

I will check at home with 3.11

Thanks
