Not so, according to the pANS C. See section 3.5.7:

  "If an object that has static storage duration is not
  initialized explicitly, it is initialized implicitly as if
  every member that has arithmetic type were assigned 0 and
  every member that has pointer type were assigned the null
  pointer constant"

As far as I know, on every known architecture supporting C the effect
is exactly the same anyways.

(Somebody, please correct me IF YOU KNOW OF A COUNTER EXAMPLE. I've
seen too many people say that it's not guaranteed by pANS C, which I
know, but I have not yet seen the name of a single machine or system
with a C compiler for which it isn't true).
