Uh, have you actually tried this? It doesnt do anything:
$ 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 -Wformat-signedness -o alfa alfa.c
$ ./alfa
-1 18446744073709551615 18446744073709551615
