   It seems that you meant to say x-=1 there.  Otherwise looping forever is
 the expected behaviour.  I've tested your code with both longs and long
 longs, and both with and without your bugfix.  Both the bugged versions
 looped forever and both the fixed versions exit almost instantly.  Are you
 sure you didn't fix the bug at the same time as you changed from long longs
 to plain longs?
