Log message:
	2004-10-26  Ed Schonberg  <schonberg@gnat.com>
	
	* exp_aggr.adb (Safe_Component): An aggregate component that is an
	unchecked conversion is safe for in-place use if the expression of the
	conversion is safe.
	(Expand_Array_Aggregate): An aggregate that initializes an allocator may
	be expandable in place even if the aggregate does not come from source.
	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the
	designated object of an allocator in place, rather than building it
	first on the stack. The previous scheme forces a full copy of the array,
	and may be altogether unsusable if the size of the array is too large
	for stack allocation.
