4.10 dune runtest fails undefined reference to caml_process_pending_signals #14

With commit ocaml/ocaml@fc788ef6b2984ab05179322d8c1e2f04dbac98d2 I get this error with dune runtest:

[   54s] Command [6] exited with code 2:

[   54s] collect2: error: ld returned 1 exit status

Not sure if this is an issue in ocaml to be resolved, or if external packages need to be tweaked to support 4.10.

Well spotted, thank you for the report. Indeed, the Graphics library relies on a part of the OCaml runtime system that changed recently. Tentative fix in #15.
