* decl.cc (gfc_get_pdt_instance): Set the PDT instance field
'f2k_derived', if not set already, to point to the given
PDT template 'f2k_derived' namespace in order to give the
PDT instance referential access to the typebound procedures
of the template.
* gfortran.h (gfc_pdt_is_instance_of): Add prototype.
* resolve.cc (resolve_typebound_procedure): If the derived type
does not have the attribute 'pdt_template' set, compare the
dummy argument to the 'resolve_bindings_derived' type like usual.
If the derived type is a 'pdt_template', then check if the
dummy argument is an instance of the PDT template. If the derived
type is a PDT template, and the dummy argument is an instance of
that template, but the dummy argument 'param_list' is not
SPEC_ASSUMED, check if there are any LEN parameters in the
dummy argument. If there are no LEN parameters, then this implies
that there are only KIND parameters in the dummy argument.
If there are LEN parameters, this would be an error, for all
LEN parameters for the dummy argument MUST be assumed for
typebound procedures of PDTs.
(resolve_pdt): Add a check for ALLOCATABLE and POINTER attributes for
SPEC_DEFERRED parameters of PDT class symbols. ALLOCATABLE and
POINTER attributes for a PDT class symbol are stored in the
'class_pointer' and 'allocatable' attributes of the '_data'
component respectively.
