Curious: the ocamlbuild bug appears to still be open upstream
<https://github.com/ocaml/ocamlbuild/issues/164>, but
https://github.com/ocaml/ocamlbuild/commit/00e05f686e15b07ac4268fcd10cf3738a5c28467
was applied with the proposed fix in ocamlbuild 0.9.0.

I suspect this means that the ocamlbuild bug was indeed fixed, and
that we should be able to reinstate the patch.

Except...  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=642835;msg=55
says the bug is present in ocamlbuild 0.10.1.  Ximin, do you remember
where that version number came from?  Is it possible that the bug is
*not* present in that version?

Thanks,
Jonathan
