You are correct.  I measured 70% & 80% (cc65 2.13 and 2.12 
respectively).  However a 30% reduction in time is still significant (or 
'much faster' IMHO) if performance is your only metric.  That is the 
problem with benchmarks.  They try to distill the value of a 
system/compiler to a single number.

Now that is bizarre given that the systems they code for are "old but 
functional".

I must admit I had forgotten the nuances of K&R when I started my 
exploration of Aztec C.  And, unfortunately, I quickly dumped my 1st Ed. 
K&R C book when the 2nd ed. ANSI version was released in the late '80s. 
  Fortunately, I was able to pick up a used copy from Amazon dirt cheap. 
  I would encourage others to do the same.
