* stdio-common/_itowa.c: Don't compile _itowa for 64-bit
platforms. * stdio-common/_itoa.c: Don't compile in _itoa and _fitoa for 64-bit platforms. * malloc/mtrace.c (tr_where): Use _fitoa_word instead of _fitoa if possible. * posix/wordexp.c (parse_arith): Use _itoa_word instead of _itoa if possible.
