* c-tree.h (default_function_array_conversion): Declare.
	* c-typeck.c (default_function_array_conversion): Export.  Correct
	comment.
	(default_conversion): Do not call
	default_function_array_conversion.  Do not allow FUNCTION_TYPE.
	(build_function_call): Call default_function_array_conversion on
	the function.
	(convert_arguments): Do not call it on the function arguments.
	(build_unary_op): Do not allow ARRAY_TYPE or FUNCTION_TYPE for
	TRUTH_NOT_EXPR.  Call default_function_array_conversion for taking
	address of ARRAY_REF.
	(build_compound_expr): Do not call
	default_function_array_conversion.
	(build_c_cast): Do not call default_function_array_conversion.
	(convert_for_assignment): Do not call default_conversion.
	(digest_init): Call default_function_array_conversion to convert
	string constants and compound literals to pointers, but not
	otherwise.
	(output_init_element): Likewise.
	(build_asm_expr): Do not call default_function_array_conversion.
	(c_process_expr_stmt): Likewise.

	FUNCTION_TYPE.
	* c-parser.c (c_parser_expression_conv): New.
	(c_parser_asm_operands, c_parser_expr_list): Add convert_p
	argument.  All callers changed.  Call
	default_function_array_conversion if convert_p.
	(c_parser_initializer, c_parser_initval): Call
	default_function_array_conversion except for string constants and
	compound literals.
	(c_parser_initelt): Call default_function_array_conversion for
	ObjC expression received.
	(c_parser_statement_after_labels): Call c_parser_expression_conv
	for return and expression statements.
	(c_parser_paren_condition, c_parser_for_statement,
	c_parser_conditional_expression): Call c_parser_expression_conv.
	(c_parser_expr_no_commas, c_parser_conditional_expression,
	c_parser_binary_expression, c_parser_cast_expression,
	c_parser_unary_expression): Call
	default_function_array_conversion.

objc:
	* objc-act.c (my_build_string_pointer): New.
	(objc_get_class_reference, get_super_receiver): Call
	my_build_string_pointer instead of my_build_string when building
	function arguments.
