As you say:
-----------------
  $   # If a.out and a.out.saved are always identical (except internal
  $   # timestamps, if any) then the compiler is deterministic.
-----------------

And I could almost swear it is also possible to (automatically) edit binaries
that are different due to different environments (i.e. think things that embed
uname -v, perl -V etc.) so that a baseline is established and _then_
checksummed, giving the correct (i.e. relevant) comparison.
