	* a-rbtgbo.adb (Clear_Tree): Assert representation invariant for lock
	status.

2011-08-31  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch5.adb: Set kind of loop parameter properly, to preserve all
	errors in B tests.

2011-08-31  Jose Ruiz  <ruiz@adacore.com>

	* sem_ch13.adb (Analyze_Aspect_Specifications): For the Priority and
	Interrupt_Priority aspects, force the analysis of the aspect expression
	(when building the equivalent pragma). Otherwise, its analysis is done
	too late, after the task or protected object has been created.
	* sem_ch9.adb (Analyze_Single_Protected_Declaration,
	Analyze_Single_Task_Declaration): Remove the code to move the aspects
	to the object declaration because they are needed in the type
	declaration.
