Alvin Wong <alvinhochun at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |alvinhochun at gmail dot com --- Comment #14 from Alvin Wong <alvinhochun at gmail dot com> --- `strftime` is another case that's affected. UCRT supports C99 formats (e.g. %F, %T) but GCC warns because of the hardcoded built-in ms_strftime format attribute, even though mingw-w64 has specified gnu_strftime.
