I'm sure it was the result of someone being familiar with the original 
architecture and compiler, and made certain decisions that compiled "in 
his favor".  When I discovered similar things I could do in my own 
environment 15 years ago, I did the same thing -- without commenting, so 
of course I confused myself a year ago trying to read the code.  I was 
shifting something right one place and then dealing with the carry; I 
kept looking for bitmask stuff later in the code when I realized after 
half an hour I was simply dividing by two :-/

So now when I optimize like silly, I keep the original code commented 
out, and then I optimize, and then I COMMENT my optimizations.
