        * trans-expr.c (select_class_proc): Remove function.
        (conv_function_val): Delete reference to previous.
        (gfc_conv_derived_to_class): Add second argument to the call to
        gfc_find_derived_vtab.
        (gfc_conv_structure): Exclude proc_pointer components when
        accessing $data field of class objects.
        (gfc_trans_assign_vtab_procs): New function.
        (gfc_trans_class_assign): Add second argument to the call to
        gfc_find_derived_vtab.
        * symbol.c (gfc_build_class_symbol): Add delayed_vtab arg and
        implement holding off searching for the vptr derived type.
        (add_proc_component): New function.
        (add_proc_comps): New function.
        (add_procs_to_declared_vtab1): New function.

        (void add_generic_specifics): New function.
        (add_generics_to_declared_vtab): New function.
        (gfc_find_derived_vtab): Add second argument to the call to
        gfc_find_derived_vtab. Add the calls to
        add_procs_to_declared_vtab and add_generics_to_declared_vtab.
        * decl.c (build_sym, build_struct): Use new arg in calls to
        gfc_build_class_symbol.
        * gfortran.h : Add vtype bitfield to symbol_attr. Remove the
        definition of struct gfc_class_esym_list. Modify prototypes
        of gfc_build_class_symbol and gfc_find_derived_vtab.
        * trans-stmt.c (gfc_trans_allocate): Add second argument to the
        call to gfc_find_derived_vtab.
        * module.c : Add the vtype attribute.
        * trans.h : Add prototype for gfc_trans_assign_vtab_procs.
        * resolve.c (resolve_typebound_generic_call): Add second arg
        to pass along the generic name for class methods.
        (resolve_typebound_call): The same.
        (resolve_compcall): Use the second arg to carry the generic
        name from the above. Remove the reference to class_esym.
        (check_members, check_class_members, resolve_class_esym,
        hash_value_expr): Remove functions.
        (resolve_class_compcall, resolve_class_typebound_call): Modify
        to use vtable rather than member by member calls.
        (gfc_resolve_expr): Modify second arg in call to
        resolve_compcall.
        (resolve_select_type): Add second arg in call to
        gfc_find_derived_vtab.
        (resolve_code): Add second arg in call resolve_typebound_call.
        (resolve_fl_derived): Exclude vtypes from check for late
        procedure definitions. Likewise for checking of explicit
        interface and checking of pass arg.
        * iresolve.c (gfc_resolve_extends_type_of): Add second arg in
        calls to gfc_find_derived_vtab.
        * match.c (select_type_set_tmp): Use new arg in call to
        gfc_build_class_symbol.
        * trans-decl.c (gfc_get_symbol_decl): Complete vtable if
        necessary.
        * parse.c (endType): Finish incomplete classes.
