        * trans-array.c (gfc_reverse_ss): Remove static attribute.
        (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
        the function call with the corresponding gfc_actual_arglist*.  Change
        code accordingly.
        (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
        now requires the actual argument list instead of the expression for
        the function call.
        * trans-array.h: Modify the prototype for
gfc_walk_elemental_function_args
        and provide a prototype for gfc_reverse_ss.
        * trans-stmt.h (gfc_trans_call): Add the scalarization code for the
case
        where an elemental subroutine has array valued actual arguments.

        * resolve.c (check_assumed_size_reference): New function to check for
upper
        bound in assumed size array references.
        (resolve_assumed_size_actual): New function to do a very restricted
scan
        of actual argument expressions of those procedures for which incomplete
        assumed size array references are not allowed.
        (resolve_function, resolve_call): Switch off assumed size checking of
        actual arguments, except for elemental procedures and intrinsic
        inquiry functions, in some circumstances.
        (resolve_variable): Call check_assumed_size_reference.
