        s-osprim-mingw.adb (Timed_Delay, Timed_Sleep): Register the base
	time when entering this routine to detect a backward clock setting
	(manual setting or DST adjustment), to avoid waiting for a longer delay
	than needed.
	(Time_Duration, To_Timeval, struct_timeval): Removed when not relevant.
	Remove handling of deferred priority change, and replace by setting the
	task priority directly, as required by AI-188.
	Update comments.
	(Max_Task_Image_Length): New constant.
	Replace Warnings (Off) by Unreferenced pragma, cleaner.
	(Dynamic_Priority_Support): Removed, no longer needed.
	(Poll_Base_Priority_Change): Ditto.
	(Set_Ceiling): Add this procedure to change the ceiling priority
	associated to a lock. This is a dummy implementation because dynamic
	priority ceilings are not supported by the underlying system.

	* a-dynpri.adb (Set_Priority): Take into account case where Target is
	accepting a RV with its priority boosted.
	Remove handling of deferred priority change, and replace by setting the
	task priority directly, as required by AI-188.

	* s-taenca.adb (Try_To_Cancel_Entry_Call): Remove special case for
	Succeeded = True.
	Remove handling of deferred priority change, and replace by setting the
	task priority directly, as required by AI-188.
	(Wait_For_Completion, Wait_For_Call, Timed_Selective_Wait): Change state
	of Self_Id earlier.

	* s-tasini.ads, s-tasini.adb (Wakeup_Entry_Caller): Relax assertion.
	(Poll_Base_Priority_Change): Removed.
	Code clean up: use SSL.Current_Target_Exception.

	* s-tasren.adb (Task_Count): Call Yield to let a chance to other tasks
	to run as this is a potentially dispatching point.
	(Call_Synchronous): Use Local_Defer_Abort.
	(Callable): Relax assertion.
	(Selective_Wait): Relax assertion in case abort is not allowed.
	Remove handling of deferred priority change, and replace by setting the
	task priority directly, as required by AI-188.

	* s-tasuti.adb (Make_Passive): Adjust assertions.
	Remove handling of deferred priority change, and replace by setting the
	task priority directly, as required by AI-188.
