I've merged #6211 (with additional improvements) into this PR because it makes more sense as one given this adds an actual CI for Windows + OCaml5. |

How about having the mingw-w64 i686 test OCaml 5.2.0 and the MSVC i686 test OCaml 4.14.2?

I think this would trigger the tests for the platform and it would be way too slow

…t more than one default version
Windows is an exception since MSVC isn't supported yet (will be in 5.3.0), and Cygwin fails when used in combination with C++ stubs. So only MinGW x86_64 is tested because it's the only one that both works and is reasonably fast to run (i686 is too slow since it's using bytecode).
…upported by master This marginally increases build time (by 30s best case scenario) but is a necessary fix

It seems that after a couple of rebase of #6189 we forgot to commit one change to
OpamStubs.ocaml5.mlwhich actually means that the file doesn't compile (since the Windows+OCaml5 combination wasn't tested in our CI).This here PR should fix this issue for good.
Backported to 2.3 in #6224
