I had a few comments on commit message and comment wordings here.
Other than that, this looks reasonable to me. I think this is the most
consistent way forward.
However in practice, there's a moderately high chance that this will break
existing code (for all the code that is built with
__USE_MINGW_ANSI_STDIO=1, which is the default for most configurations
with msvcrt.dll, and with UCRT you'll also get this if you e.g. include
libstdc++ headers). Like, I'm quite sure that this will break some user's
code.
But on the other hand, our current state is inconsistent, so this does
make things better.
What do Liu Hao and Jacek think about it?
