[Libguestfs] [PATCH 0/9] build: Require OCaml >= 4.02.

[Richard W.M. Jones]

Per my previous email:
https://www.redhat.com/archives/libguestfs/2017-September/msg00203.html
I'd like to talk about requiring a more modern version of the OCaml
compiler.

These commits show some of the code changes which would be possible
with OCaml >= 3.12 [which it turns out we already require by accident]
and also with OCaml >= 4.02.  The latter is my favoured option.

Rich.
