  o Minor features (portability):
    - Try to prevent a compiler warning about printf arguments that could
      sometimes occur on MSYS2 depending on the configuration.
      Closes ticket 40355.
Prefer use of __MINGW_PRINTF/SCANF_FORMAT if available. Mingw headers sometimes like to define alternative scanf/printf format attributes depending on whether they're using clang, UCRT, MINGW_ANSI_STDIO, or the microsoft version of printf/scanf. This change attempts to use the right one on the given platform. This is an attempt to fix part of #40355. 2021-11-05 12:08:48 -04:00			`o Minor features (portability):`
