Julien Lepiller (10):
  gnu: Add ocaml-base64.
  gnu: Add ocamlify.
  gnu: Add omake.
  gnu: Add ocaml-batteries.
  gnu: Add ocaml-pcre.
  gnu: Add ocaml-expect.
  gnu: Add ocaml-fileutils.
  gnu: Add ocaml-oasis.
  gnu: Add ocaml-js-build-tools.
  gnu: Add ocaml-bin-prot.

This has been discussed a couple of times on the mailing list. IIRC
setting up LD_LIBRARY_PATH to point to $glibc/lib fixes it.

See e.g. https://lists.gnu.org/archive/html/help-guix/2017-01/msg00028.html

or https://lists.gnu.org/archive/html/guix-devel/2016-11/msg01104.html

for a patch with a (suboptimal) fix. I should brush up this package.. :P

Please clarify what the exception is, or where to find the full text.

Please use @enumerate here too.

Hopefully someone else can chime in on the helper functions above, if it
works I'd say they are fine. LGTM!

I don't know anything about ocaml, but the patches reads fine to me.

One thing that strikes me is the usage of native-inputs; I assume it's
because the packages are not referenced, but bear in mind that they are
built for the architecture of the build machine, and not for the target
system.

E.g. `guix build --system=i686-linux ocamlify` will add 64-bit
native-inputs even if the final product is supposed to be 32-bit. Not
sure if that will cause problems or not.

> I'm pretty sure number 9 and 10 can be improved, any idea?

Not from me, I'd say it looks fine :-)

I use native-inputs because the build system needs binaries (not
libraries) from these packages.

Just to be sure, I'll cross-compile them. I'll send updated patches
soon.

Thanks for your review :)
