Thanks for the patches!

Have you tried updating dune to the latest version that builds with
ocaml 4.07?

Actually 3, there are ocaml 4.07, 4.09 and 4.11 currently. I'm working
on a bootstrap for ocaml 4.07 (ocaml builds from a binary version of
itself), so I don't think it'll disappear soon, but at least we can try
and make ocaml4.07-* packages disappear :)

pretty sure they build with at least ocaml-4.09 now, I'll see what I
can do :)

Yeah, could you provide an additional patch for that?

Thank you! I've sent some remarks to your patches, but generally LGTM :)
