ocamlc relies on temporary files as well. In general, whatever is done for ocamlopt should be done for ocamlc as well. > Therefore, we need a way to make these names determinist.

The generation of temporary file names uses its own RNG (cf. stdlib/filename.ml), that would be the place to change its initialization. I am a bit worried to have predictable names for files that end up in /tmp, though. For building packages, it should be fine I guess. I have to think more about it.
