	* sem_type.adb, sem_ch10.adb, freeze.adb, sem_ch6.adb, exp_disp.adb:
	Minor reformatting.

	* exp_attr.adb (Size): Remove unnecessary check for types with
	unknown discriminants.	That was causing the compiler to build
	a function call _size(T), where T is a type, not an object.

2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Extended_Primitive_Ops): Exclude overriding
	primitive operations of a type extension declared in the package
	body, to prevent duplicates in extended list.

2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Analyze_Component_Declaration): If the component is
	an unconstrained synchronized type with discriminants, create a
	constrained default subtype for it, so that the enclosing record
	can be given the proper size.
	* sem_util.adb (Build_Default_Subtype): If the subtype is created
	for a record discriminant, do not analyze the declarztion at
	once because it is added to the freezing actions of the enclosing
	record type.
