round() was not added to math.h until C99 . If you are using an older compiler (especially lcc) or you do not have --std99 in effect then you will not have access to round()
bzero is in strings.h not in string.h -- though you will find reference to it being in string.h. I did not investigate to find out if it moved at some point.
