It's "obvious" only if you take "optimizing references to variables in C
is bad" as an axiom.  You seem to take it as an axiom.  Others do not.

1) Ritchie's compiler wasn't PCC-based

2) it only reiterates that if you consider optimizing references to
   variables in that fashion to be a bug.  Again, others do not.

Note that in the cases where you consider X to be true, and others do
not, it should be quite apparent that repeating "X is true" 5000 times
is only going to annoy the others, not convince them.

Just because *you* consider it to be a bug, does that make it a bug even
if 99% of the users of the Ritchie compiler did not?  Yeesh.  Talk about
word-twisting; the pretzel factory seems to be working overtime....
