Correcting myself. Here is why you cannot use %zi:

    $ cat alfa.c
    #define __USE_MINGW_ANSI_STDIO 1
    #include <stdio.h>
    int main() {
      printf("%zi %zu %llu\n", __SIZE_MAX__, __SIZE_MAX__, __SIZE_MAX__);
    }

    $ x86_64-w64-mingw32-gcc -o alfa alfa.c

    $ ./alfa
    -1 18446744073709551615 18446744073709551615
