Windows 7 is EOL since 2020. Current OCaml releases don't work in Windows 7 either as far as I know. Any reason why you are stuck on such old version of Windows?

I'm poor! It's a computer I was given in 2008, and I was teached "if it ain't broke, don't fix it". I don't need more for coding. In subtitle, it was to underline that a (small?) change in last release probably broke Win7 support that was ok up to Dune 3.21. It's not documented, I won't have tried four times overwise. Also, notice that I still build Geneweb with Win7 support on modern toolchain/actions CI without any problem. Our genealogy tool don't need powerfull computers.

Fair enough! I try to provide a fallback in nojb@039206c. Are you able to try it?
