// Get standard-compliant stdio functions under MinGW and MinGW-w64.
// This #define ensures that C99 and POSIX compliant stdio functions are
// available with MinGW-w64 (both 32-bit and 64-bit). Modern MinGW-w64 adds
// this automatically, for example, when the compiler is in C99 (or later)
// mode when building against msvcrt.dll. It still doesn't hurt to be explicit
// that we always want this and #define this unconditionally.
//
// With Universal CRT (UCRT) this is less important because UCRT contains
// C99-compatible stdio functions. It's still nice to #define this as UCRT
// doesn't support the POSIX thousand separator flag in printf (like "%'u").
