	* g-socket.adb (Host_Entry): Introduce intermediate copy of
	memory location pointed to by Hostent_H_Addr, as it might not
	have sufficient alignment.

	* repinfo.adb (List_Rep_Info): Set the value of Unit_Casing before
	calling subprograms which may read it.

	* einfo.adb: Remove Loop_Entry_Attributes from the usage of
	nodes. Flag 260 is now used.
	(Has_Loop_Entry_Attributes): New routine.
	(Loop_Entry_Attributes): Removed.
	(Set_Has_Loop_Entry_Attributes): New routine.
	(Set_Loop_Entry_Attributes): Removed.
	(Write_Entity_Flags): Write out Flag 260.
	(Write_Field10_Name): Remove the output for Loop_Entry_Attributes.
	* einfo.ads: Remove attribute Loop_Entry_Attributes,
	its related comment and uses in nodes.	Add new attribute
	Has_Loop_Entry_Attributes, related comment and uses in loop nodes.
	(Has_Loop_Entry_Attributes): New routine and pragma Inline.
	(Loop_Entry_Attributes): Removed along with pragma Inline.
	(Set_Has_Loop_Entry_Attributes): New routine and pragma Inline.
	(Set_Loop_Entry_Attributes): Removed along with pragma Inline.

	block. Move the processing of controlled object at the end of
	loop expansion.
	* sem_attr.adb (Analyze_Attribute): Do not chain attribute
	'Loop_Entry to its related loop.
	* sem_ch5.adb (Analyze_Loop_Statement): Add local variable
	Stmt. When the iteration scheme mentions attribute 'Loop_Entry,

	routine.
	(Subject_To_Loop_Entry_Attributes): New routine.
