	* c-typeck.c (c_convert_parm_for_inlining): Add argnum, which
	is the argumnt we are processing so that warnings and errors
	will have that information.
	* c-tree.h (c_convert_parm_for_inlining): Add argnum.
	* lang-hooks-def.h
	(lhd_tree_inlining_convert_parm_for_inlining): Likewse.
	* langhooks.c (lhd_tree_inlining_convert_parm_for_inlining): Likewise.
	* langhooks.h (convert_parm_for_inlining): Likewise.
	* tree-inline.c (initialize_inlined_parameters): Compute and
	pass argnum down.
