If possible, it would be best not to update pcre at the same time. You
can try updating first, then switch to the latest ocaml, or the other
way around. If it's really not possible, please add the version number
to the commit message.

Are you sure there are no tests? There used to be tests that could be
found at the top-level directory (#:test-target "."). Doesn't that work
anymore?

Otherwise, looks good.
