That is quite interesting. What happens if you remove the "register" 
keyword? In theory, it should never be necessary - the compiler should 
be slick enough to work out when it's more efficient to use a register 
variable.

Also, I wonder if tinkering with the optimization level might change the 
object code you get here.
