3829 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
3830 the function call with the corresponding gfc_actual_arglist*. Change
3832 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
3833 now requires the actual argument list instead of the expression for
3835 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
3836 and provide a prototype for gfc_reverse_ss.
3837 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
3838 where an elemental subroutine has array valued actual arguments.
3844 * resolve.c (check_assumed_size_reference): New function to check for upper
3845 bound in assumed size array references.
3846 (resolve_assumed_size_actual): New function to do a very restricted scan
3847 of actual argument expressions of those procedures for which incomplete
3848 assumed size array references are not allowed.
3849 (resolve_function, resolve_call): Switch off assumed size checking of
3850 actual arguments, except for elemental procedures and intrinsic
3851 inquiry functions, in some circumstances.
3852 (resolve_variable): Call check_assumed_size_reference.

3868 use associated character functions lengths.
3869 * expr.c, gfortran.h, resolve.c: Updated copyright years.
3871 2006-01-03 Steven G. Kargl <kargls@comcast.net>
