	* ipa-cp.c (ipcp_init_stage): Calls ipa_set_called_with_variable_arg
	instead of setting number of formal parameters to zero.
	(ipcp_init_stage): Do not set the number of actual parameters to zero 
	either.

	which are called with variable number of arguments.

	called with variable number of arguments.

	number of parameters.
