I'm trying to get the available field working in camlp4 so that we can select a system camlp4 if its a preinstalled switch. I have the following camlp4 packages:

This works fine OPAM 1.2, but OPAM 1.1.1 complains with a parse error. Is there
anything that'll work for both?
See https://travis-ci.org/ocaml/opam-repository/jobs/34006191
and https://github.com/ocaml/opam-repository/pull/2558
errors are:
[WARNING] Errors while parsing camlp4.4.02.0 OPAM file, skipping.
[WARNING] Errors while parsing camlp4.4.02.0+system OPAM file, skipping.
[WARNING] Errors while parsing camlp4.4.02.0 OPAM file, skipping.
[WARNING] Errors while parsing camlp4.4.02.0+system OPAM file, skipping.
(Also, an env var to turn these parse warnings into failures would be a useful Travis knob to have in 1.2 perhaps)
