	* exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
	components of the corresponding record, take into account component
	definitions that are access definitions.
	(Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
	procedure is not considered a dispatching call and will be expanded
	properly.
