I don't know what ANSI standard says, but as I understand the post increment 
operator must increment after use so the right-most value will be 1 because is 
the value of i before the printf line, then gcc push the value to the stack. 
Now i *was used* and hence gcc applies the post increment so now i=2, then gcc 
pushes 2 and increments so you get 2 and 3.
