 353         FMT_D.

 360         * io/format.c (parse_format_list): Implement the E0 exponent
 361         width to provide smallest possible width for exponent fields.
 362         Refactor code for correct parsing and better readability of the
 363         code.
 364         * io/io.h (write_real_w0): Change interface to pass in pointer
 365         to fnode.
 366         * io/transfer.c: Update all calls to write_real_w0 to use the
 367         new interface.
 368         * io/write.c ((write_real_w0): Use the new interface with fnode
 369         to access both the decimal precision and exponent widths used in
 370         build_float_string.
 371         * io/write_float.def (build_float_string): Use the passed in
 372         exponent width to calculate the used width in the case of E0.
