[Message part 3 (text/plain, inline)]

Hi, the attachment is a build log of compiling Emacs on Windows 10 in Msys2's
UCRT environment, most of the warnings are from windows related files, so I
think it may be helpful to report it.

Thanks, I fixed the warnings that I care about.  The rest should be
ignored.

> Btw, should I keep using `make V=1` ?

Not necessary, thanks.

I'm therefore closing this bug.
