(POINTER): Remove. All uses changed to void *.
(obstack_alloc_failed_handler, CALL_CHUNKFUN, CALL_FREEFUN, _obstack_begin, _obstack_begin_1, _obstack_allocated_p) (defined __STDC__ && __STDC__)]: Remove nonprototyped code. Include <stdlib.h> unconditionally. (_obstack_begin, _obstack_begin_1, _obstack_newchunk, _obstack_allocated_p, _obstack_free, obstack_free, _obstack_memory_used, print_and_abort): Define using prototypes. (obstack_1grow, obstack_1grow_fast, obstack_alloc, obstack_base, obstack_blank, obstack_blank_fast, obstack_copy, obstack_copy0, obstack_finish, obstack_grow, obstack_grow0, obstack_make_room, obstack_next_free, obstack_object_size, obstack_room) [0]: Remove unused, unprototyped code.
