Aren’t both wrong? By definition %i is a signed integer, and size_t is unsigned.
So %zu or %llu would be more correct:

http://wikipedia.org/wiki/C_data_types

They all seem to do the job though:

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

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

    $ ./alfa
    1 1 1
