Actually I think in this case they would be. Most compilers do this by
default IIRC (if you'd like to see for yourself, try the attached test.)
Still, I think it would be prudent to put the 0 in there anyway, sine I
don't think there's a standard that says compilers have to do this so
there could potentially be portability problems. 

HTH,
