The elevator_name field in struct elevator_type is declared as an array of characters (ELV_NAME_MAX size) but in practice used as a string pointer with its initialization done statically within each elevator elevator_type structure declaration. Change the declaration of elevator_name to the more appropriate "const char *" type.
