You're right. This will be fixed in 3.12.1.

Thanks.
We just started here to port ocaml to mingw-w64, question arises:
Which files need adoption?
I have seen that in asmrun the amd64.S needs patches and in asmcomp the emit
and proc mls.
Do I miss files?
Greetings
Christoph

We started to have some version that at least links (with patched flexdll) but
runs in a nice segfault already ;)
Attached are the current changed states, any ideas where to look?
Atm not seeing the obvious fault :/
