Old returns -1: error 0: no area (1: point in area) -2: island !!

Possible new area is not created by this function, so that old boundaries participating in this area are left without area information even if form new area.

Write Plus_head to file.
ptr->off_t_size is used for both coor and topo files, but their sizes (ptr->coor_size for coor and no variable for topo) can be different. If either file is greater than PORT_LONG_MAX, ptr->off_t_size must be 8. This function determines this value of ptr->off_t_size and writes it to the file.
