Ah - actually, we do still use flexdll on Cygwin, so I expect this _is_ related.

Just double-checking that this won't be merged until opam 2.1.0 is released?

https://github.com/ocaml/opam-file-format/pull/11/commits/3632a6ded471681347efd663a55faaf8c4969275 contains an unrelated, but important, change to the encoding of strings containing newlines.

I can confirm that this is working on MSVC 4.06-4.14 with only 4.06-4.10 having the dummy module in camlp_streams.cmxa. ~I'll double-check the macOS ones tomorrow when I'm near my old...

Ping @jonludlam and @sabine just to determine who should own the issue 🙂. The module documentation is on ocaml.org at https://ocaml.org/p/camlp-streams/latest/doc/Stream/index.html and https://ocaml.org/p/camlp-streams/latest/doc/Genlex/index.html so the confusion is why https://ocaml.org/p/camlp-streams/latest/doc/index.html has...

Given the contortions that the build has to go through to work on all 4.x versions correctly, I'm wondering if the dynamic dune file may be implicated - in which...

There are third and fourth ways, the third of which I’ll do shortly: - Insert a dummy module in the library for these old versions (this fixes MSVC as well)....

Linking in https://github.com/ocaml/opam-repository/pull/26183 and https://github.com/ocaml/opam-repository/issues/26198 for context. This is definitely something we should be able to do better. It's tempting simply to keep adding global variables, but I believe that...

I don't know - that test also has a `Thread.delay` in it! Although at a cursory glance, it'd be surprising if it's actually the problem. I liked this approach last...
