size_t is declared as unsigned int on 32-bit and unsigned long on 64-bit. As a
result, following code will emit a warning on amd-64:
printf ("%u\n", sizeof (int));
test.c:5: warning: format ‘%u’ expects type ‘unsigned
int’, but argument 2 has type ‘long unsigned int’
but changing the format would then fail on ia-32:
printf ("%lu\n", sizeof (int));
test.c:5: warning: format ‘%lu’ expects type ‘long unsigned
int’, but argument 2 has type ‘unsigned int’
there seems to be no way to satisfy this other than a cast, which seems a bit
awkward. Is there any reason for size_t not being "unsigned long" consistently
on all platforms?

%Zd is a GNUism and assumes a signed type (e.g. ssize_t), %zu is ISO C
