* Object.m: Fix signed/unsigned warning. * Protocol.m: Likewise. * archive.c: Always include stdlib.h. (objc_read_short, objc_read_unsigned_short, objc_read_int, objc_read_long, __objc_read_nbyte_uint, __objc_read_nbyte_ulong): Fix signed/unsigned warning. (objc_write_type, objc_read_type, objc_write_types, objc_read_types): Ensure ctype 8-bit safety. (__objc_no_write, __objc_no_read): Mark unused parameters. * class.c (class_table_setup): Specify void arg. * encoding.c (atoi, objc_sizeof_type, objc_alignof_type, objc_skip_typespec, objc_skip_offset, objc_layout_structure_next_member): Ensure ctype 8-bit safety.
