re PR fortran/39630 ([F03] Procedure Pointer Components) 

2009-07-25  Janus Weil  <janus@gcc.gnu.org>

	PR fortran/39630
	* decl.c (match_ppc_decl): Implement the PASS attribute for procedure
	pointer components.
	(match_binding_attributes): Ditto.
	* gfortran.h (gfc_component): Add member 'tb'.
	(gfc_typebound_proc): Add member 'ppc' and make 'pass_arg' const.
	* module.c (MOD_VERSION): Bump module version.
	(binding_ppc): New string constants.
	(mio_component): Only use formal args if component is a procedure
	pointer and add 'tb' member.
	(mio_typebound_proc): Include pass_arg and take care of procedure
	pointer components.
	* resolve.c (update_arglist_pass): Add argument 'name' and take care of
	optional arguments.
	(extract_ppc_passed_object): New function, analogous to
	extract_compcall_passed_object, but for procedure pointer components.
	(update_ppc_arglist): New function, analogous to
	update_compcall_arglist, but for procedure pointer components.
	(resolve_typebound_generic_call): Added argument to update_arglist_pass.
	(resolve_ppc_call, resolve_expr_ppc): Take care of PASS attribute.
	(resolve_fl_derived): Check the PASS argument for procedure pointer
	components.
	* symbol.c (verify_bind_c_derived_type): Reject procedure pointer
	components in BIND(C) types.
