512 and fix it if it is a component reference.
513 (build_array_ref): Simplify handling of class array refs by
514 passing the vptr to gfc_build_array_ref rather than generating
515 the pointer arithmetic in this function.

578 allowed outside a derived type definition.

580 type_param_spec_list on entry and free them on exit.

582 formal symbol to the f2k_derived namespace.

605 type parameter spec lists. Add the new field 'spec_type' to
606 this structure. Add 'param_list' fields to gfc_symbol and
607 gfc_expr. Add prototypes for gfc_insert_kind_parameter_exprs,
608 gfc_insert_parameter_exprs, gfc_add_kind, gfc_add_len,
609 gfc_derived_parameter_expr and gfc_spec_list_type.
610 * interface.c (gfc_compare_derived_types): Treat PDTs in the
611 same way as sequence types.

616 instance.

619 appear here. Copy the type parameter spec list to the expr for
620 the allocatable entity. Free 'type_param_spec_list'.

622 more trailing whitespace to remove.

631 namespace symroot to the f2k_derived namespace.
632 *primary.c (match_keyword_arg, gfc_match_actual_arglist): Add
633 modifications to handle PDT spec lists. These are flagged in
634 both cases by new boolean arguments, whose prototype defaults
635 are false.
636 (gfc_match_structure_constructor, match_variable): Remove yet
637 more trailing whitespace.
638 * resolve.c (get_pdt_spec_expr, get_pdt_constructor): New
639 functions.
640 (resolve_structure_cons): If the constructor is a PDT template,
641 call get_pdt_constructor to build it using the parameter lists
642 and then get the specific instance of the PDT.
643 (resolve_component): PDT strings need a hidden string length
644 component like deferred characters.

658 as appropriate for PDT symbols.
659 (gfc_trans_deferred_vars): Allocate/deallocate PDT entities as
660 they come into and out of scope. Exclude pdt_types from being
661 'gcc_unreachable'.
662 (gfc_trans_subcomponent_assign): PDT array components must be
663 handles as if they are allocatable.
664 * trans-stmt.c (gfc_trans_allocate): Handle initialization of
665 PDT entities.
666 (gfc_trans_deallocate): Likewise.
667 * trans-types.c (gfc_get_derived_type): PDT templates must not
668 arrive here. PDT string components are handles as if deferred.
669 Similarly, PDT arrays are treated as if allocatable. PDT
670 strings are pointer types.

672 way as deferred characters.
