	* c-exp.y (YYSTYPE): Add typed_val_decfloat for decimal
	floating point in YYSTYPE union.
	(DECFLOAT) Add token and expression element handling code.
	(parse_number): Parse DFP constants, which end with suffix 'df',
	'dd' or 'dl'.  Return DECFLOAT.
	* eval.c (evaluate_subexp_standard): Call value_from_decfloat to
	handle OP_DECFLOAT.
	* expression.h (enum exp_opcode): Add an opcode (OP_DECFLOAT)
	for DFP constants.
	(union exp_element): Add decfloatconst to represent DFP
	elements, which is 16 bytes by default.
	* parse.c (write_exp_elt_decfloatcst): New function to write a
	decimal float const into the expression.
	(operator_length_standard): Set operator length for OP_DECFLOAT
	to 4.
	* parser-defs.h (write_exp_elt_decfloatcst): Prototype.
	* valarith.c (value_neg): Add code to handle the negation
	operation of DFP values.
	* value.c (value_from_decfloat): New function to get the value
	from a decimal floating point.
	* value.h (value_from_decfloat): Prototype.
