3876 now requires the actual argument list instead of the expression for
3878 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
3879 and provide a prototype for gfc_reverse_ss.
3880 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
3881 where an elemental subroutine has array valued actual arguments.
