	* sem_ch13.adb (Size_Too_Small_Error): Fix the error message format.

2016-05-02  Ed Schonberg  <schonberg@adacore.com>

	* exp_prag.adb (Expand_attributes_In_Consequence,
	Expand_Attributes): If the prefix of'Old is an unconstrained type,
	for example an unconstrained formal of the enclosing subprogram,
	create an object declaration with an expression to obtain the
	actual subtype of the temporary.
