Still more obscure than using 'a' directly.  Furthermore, using the array
notation directly removes the need for _ANY_ pointer increment in the loop
(whether it is automatically scaled or not).  Other than that, the code
is now nearly identical to the code I gave as best - the array indexing
is still done _automatically_ by the compiler.  Since the supposed advantage
of using pointers was _not_ to rely on the compiler for optimizing the
index calculations, this version doesn't support Peter Grandi's claims.
