Write a 'bzerov' function, which takes a volatile first
parameter.  Presumably you could just copy the source
for bzero and change the 1st parameter declaration...


write a dumb 'bzerov' macro, which casts the first
parameter to be pointer to volatile char, and then
loops over it setting to zero one byte at a time.
