... and ten seconds after I posted that it failed again. Looks like binutils
isn't quite ready for DWARF 5 on Windows yet :(

OK, that works: ignore me, in my case it was just using a too old binutils.
(The error message emitted is... unhelpful: exec format error, really?)

After reverting the change, the compilation succeeds. However, this is a
temporary solution.

Why did you add me in CC without asking for my acknowledgement?
If you had asked MSYS2 people, I am pretty sure you would have received more
constructive suggestions.

So you need to figure it out, most people here don't have any access to
