	parameters. Add checks for decimal, sign, and blank. (st_wait): New stub.
	* format.c: (format_lex): Add format specifiers DP, DC, and D.
	(parse_format_list): Parse the new specifiers.
	* write.c (write_decimal): Use new sign enumerators to set the sign.
	(write_complex): Handle decimal comma and semi-colon separator.
	(nml_write_obj): Likewise.
	* write_float.def: Revise sign enumerators. (calculate_sign): Use new
	sign enumerators. (output_float): Likewise. Use new decimal_status flag
