I wonder in what cases you want to stringify those literals... if it's
something that you want to show the user you either:

  a) know the value in advance, and then you probably want to show
     "4 GiB" instead of "4294967296 bytes"

  b) don't know the value in advance (it's a variable), but then you
     can't use these macros.

Am I missing anything?
