- Turned on warning level 4 just to see what it would produce: a lot of

warnings. At first, I was going to try and clean them all up. Then I decided
  that was a worthless cause and went about just acting on the ones that
  might actually be helpful:
   C4189 (local variable is initialized but not referenced)
   C4702 (unreachable code)
   C4512 (assignment operator could not be generated)
