* cpphash.h (struct cpp_buff): Make unsigned.
(_cpp_get_buff): Take length of size_t. (_cpp_unaligned_alloc): New. (BUFF_ROOM, BUFF_FRONT, BUFF_LIMIT): New. (struct cpp_reader): Remove ident_pool. Add u_buff. * cppinit.c (cpp_create_reader): Initialize u_buff, not ident_pool. (cpp_destroy): Destroy u_buff, not ident_pool. * cpplex.c (parse_number, parse_string, save_comment, cpp_token_as_text): Update to use the unaligned buffer. (new_buff): Make unsigned. (_cpp_unaligned_alloc): New. * cpplib.c (glue_header_name): Update to use the unaligned buffer. * cppmacro.c (new_number_token, builtin_macro, stringify_arg): Similarly. (collect_args): Make unsigned. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@45858 138bc75d-0d04-0410-961f-82ee72b054a4
