When using __attribute__((format(...)) on functions, GCC on Windows assumes MS-specific format string by default, even if the underlying stdio implementation is ANSI-compliant (either MS Unicersal CRT or MinGW implementation). Wrap attribute into a macro that forces GNU-specific format string when using GCC.
