Believe it or not, this has been completely unchanged since INN 1.0.  :)

I believe that when innd.h gets included by innd.c, (with EXTERN defined
to be nothing), it gets declared as a static global and hence gets
initialized to all zeroes, so I think that the above assignments are
basically equivalent to = 0.  Feel free to make MyAddress go away.
