I'm not.  I'm only looking at *released* versions of Windows, but at least
considering what comments had to say about old preview releases as ways in
which this code might potentially be mangled by a compiler.

I was on MSYS2's discord for a while, but I found that between the time
zone differences and my own feeling that I needed to keep up with all the
messages I had to give up on that.  I try to prune my Github notifications
down to a level where I can keep up with pieces I'm interested in without
getting overwhelmed.

I seem to remember that IRC doesn't deliver a backlog of messages from
when you're offline, so perhaps it would be worth a try.
