	* switch-c.adb, bindgen.adb: Minor reformatting.

2015-02-20  Ed Schonberg  <schonberg@adacore.com>

	* sem_prag.adb (Analyze_Pragma, case Type_Invariant):
	Invariant'class is allowed on an abstract type.

2015-02-20  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Access_Definition): If the access definition is
	for a protected component and defines an access to protected
	subprogram, do not create an itype reference for it because a
	full type declaration will be built in order to generate the
	proper equivalent type.
	(Analyze_Subtype_Declaration): Add information of incomplete
	subtypes, for Ada 2012 extended uses of incomplete types.
