* c-expy. (operator_stoken): New function.

	(OPERATOR): New token.
	(NEW): New token.
	(DELETE): New token.
	(operator): New rule.
	(name): Add operator.
	(ident_tokens): Add "new", "delete", and "operator".
	* gdbtypes.c (rank_one_type): Don't complain about
	void pointer conversion badness if both types are
	void pointers.
