It's a #define with a string snippet guaranteed to be the right escape 
sequence to print out a uint64_t in printf.  Using it generally involves 
taking advantage of automatic string constant concatenation, ala the 
following snippet from our current hdparm.c:

  printf("(%"PRIu64" GB)\n", bbbig/1000);

Yeah, you have to supply your own "%" so you can do things like specify how 
many digits you want, zero padding, etc.
