	* gigi.h: (build_allocator): Add arg IGNORE_INIT_TYPE.

	* trans.c (call_to_gnu): Issue a warning for users of Starlet when
	making a temporary around a procedure call because of non-addressable
	actual parameter.
	(process_freeze_entity): If entity is a private type, capture size
	information that may have been computed for the full view.
	(tree_transform, case N_Allocator): If have initializing expression,
	check type for Has_Constrained_Partial_View and pass that to
	build_allocator.
	(tree_transform, case N_Return_Statement): Pass extra arg to
	build_allocator.

	* decl.c (annotate_value): Remove early return if -gnatR is not
	specified.
	(gnat_to_gnu_field): Don't make a packable type for a component clause
	if the position is byte aligned, the field is aliased, and the clause
	size isn't a multiple of the packable alignment. It serves no useful
	purpose packing-wise and would be rejected later on.
	(gnat_to_gnu_entity, case object): Pass extra arg to build_allocator.

	PR ada/20515
	(gnat_to_gnu_entity): Remove use of macro _WIN32 which is wrong in the
	context of cross compilers. We use TARGET_DLLIMPORT_DECL_ATTRIBUTES
	instead.
	(create_concat_name): Idem.
