Hmm - what compiler actually is that? There are a few things you get that I don’t seem to see, and some things look “wrong”...

What does “g++ -v” actually report in your Msys2 shell?

    I'll await the OP's response to that question as well.

    What it "should be", assuming msys2 was installed recently (today),
    I get version 11.2.0 (Rev2):

Compiling gzlib.c...
gzlib.c: In function ‘gz_open’:
gzlib.c:243:20: warning: implicit declaration of function ‘_wopen’; did you mean ‘fwopen’? [-Wimplicit-function-declaration]
  243 |         fd == -2 ? _wopen(path, oflag, 0666) :
      |                    ^~~~~~
      |                    fwopen

That looks odd - I don't recall my “fresh” build from earlier today doing that. 
This may well be the warning from PNG that Greg mentions, though I imagine.

    Actually, that's not one of the warnings I got.

    I opened issue #296 regarding the warnings I got this morning:
