3837 * trans-array.c (gfc_reverse_ss): Remove static attribute.
3838 (gfc_walk_elemental_function_args): Replace gfc_expr * argument for
3839 the function call with the corresponding gfc_actual_arglist*. Change
3841 (gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
3842 now requires the actual argument list instead of the expression for
3844 * trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
3845 and provide a prototype for gfc_reverse_ss.
3846 * trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
3847 where an elemental subroutine has array valued actual arguments.
3853 * resolve.c (check_assumed_size_reference): New function to check for upper
3854 bound in assumed size array references.
3855 (resolve_assumed_size_actual): New function to do a very restricted scan
3856 of actual argument expressions of those procedures for which incomplete
3857 assumed size array references are not allowed.
3858 (resolve_function, resolve_call): Switch off assumed size checking of
3859 actual arguments, except for elemental procedures and intrinsic
3860 inquiry functions, in some circumstances.
3861 (resolve_variable): Call check_assumed_size_reference.

3877 use associated character functions lengths.
3878 * expr.c, gfortran.h, resolve.c: Updated copyright years.
3880 2006-01-03 Steven G. Kargl <kargls@comcast.net>
