The incredibly ugly solution I've used in the past is

// printf macros for size_t, in the style of inttypes.h
#ifdef _LP64
#define __PRIS_PREFIX "z"
#else
#define __PRIS_PREFIX
#endif
#define PRIuS __PRIS_PREFIX "u"

and then
  printf("size is %" PRIuS "\n", sizeof(foo));

Much nicer just to avoid using size_t in printf's if you can.
