gcc/fortran
	PR fortran/89707
	* decl.cc (gfc_get_pdt_instance): Copy the typebound procedure
	field from the PDT template. If the template interface has
	kind=0, provide the new instance with an interface with a type
	spec that points to that of the parameterized component.
	(match_ppc_decl): When 'saved_kind_expr' this is a PDT and the
	expression should be copied to the component kind_expr.
	* gfortran.h: Define gfc_get_tbp.

gcc/testsuite/
	PR fortran/89707
	* gfortran.dg/pdt_43.f03: New test.
