[Bug c/43991] New: typeof (size_t) inconsistency

[jimsmite at rocketmail dot com]

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?
