* infcall.c (call_function_by_hand): When STRUCT_RETURN, always
	use STRUCT_ADDR.  When not using "struct return convention", pass
	"0" to "value_being_returned".  Add FIXMEs.
	* infcmd.c (print_return_value): Pass an explicit 0/1 to
	value_being_returned.  Add comments.
	* values.c (value_being_returned): Add fixme.
	* hppa-tdep.c (hppa_extract_struct_value_address): Add FIXME.
	(hppa_value_returned_from_stack): Add FIXME.

is already being done in in the inferior function call code.
In fact, when inferior function calls are made async, this
