    * gfortran.dg/c_funloc_tests_3.f03: New test case.
    * gfortran.dg/c_ptr_tests_7.f03: Ditto.
    * gfortran.dg/c_ptr_tests_8.f03: Ditto.
    * gfortran.dg/c_ptr_tests_9.f03: Ditto.
    * gfortran.dg/c_loc_tests_7.f03: Ditto.
    * gfortran.dg/c_funloc_tests_3_funcs.c: C functions for new test
    case c_funloc_tests_3.
    * gfortran.dg/binding_label_tests_14.f03: New test case.
    * gfortran.dg/c_ptr_tests_10.f03: Ditto.
    * gfortran.dg/c_ptr_tests_8_funcs.c: C functions for new test case
    c_ptr_tests_8.
    * gfortran.dg/c_ptr_tests_7_driver.c: C Driver for c_ptr_tests_7.
    * trans-expr.c (gfc_conv_initializer): Convert expressions that
    use C_NULL_PTR or C_NULL_FUNPTR to constant expressions for NULL.
    (gfc_conv_expr): Convert typespecs for iso_c_binding derived types
    to INTEGER(kind=gfc_index_integer_kind) (size of void *).
    * symbol.c (gen_special_c_interop_ptr): Create C_PTR or C_FUNPTR
    if not listed by user in only clause and are needed.
    (generate_isocbinding_symbol): Create C_PTR or C_FUNPTR if not
    listed by user in only clause and are needed.
    * decl.c (verify_c_interop_param): Report error for procedures
    that are not BIND(C) but need to be a C interoperable parameter.
    * trans-const.c (gfc_conv_constant): Convert expressions for
    C_NULL_PTR and C_NULL_FUNPTR to constant expressions for NULL.
    * trans-types.c (gfc_typenode_for_spec): Convert typespecs for
    iso_c_binding derived types.
    (gfc_get_derived_type): Set the backend_decl of the iso_c_binding
    derived types to ptr_type_nodes (void *), of type
    INTEGER(kind=gfc_index_integer_kind), and f90_type of BT_VOID.
    Removed code that was used when the tree for the iso_c_binding
    derived types represented derived types instead of ptr_type_node.
    * resolve.c (is_scalar_expr_ptr): Allow for arrays of size 1.
    (gfc_verify_binding_labels): Fixed ICE caused by NULL pointer.
    (resolve_fl_procedure): Clear the is_bind_c attribute if the
    symbol has an error (prevents duplicate messages).
    * trans-decl.c (gfc_create_module_variable): Make sure the
    typespecs for iso_c_binding derived types are converted for
    ptr_type_node.
    (generate_local_decl): Ditto.
    * trans-io.c (transfer_expr): Convert expressions for
    iso_c_binding derived types.
    * iso_c_generated_procs.c (c_f_pointer_i1): Made C pointer
    parameter of type (void *).  Fixed whitespace and coding style.
    (c_f_pointer_i2): Ditto.
    (c_f_pointer_i4): Ditto.
    (c_f_pointer_i8): Ditto.
    (c_f_pointer_i16): Ditto.
    (c_f_pointer_r4): Ditto.
    (c_f_pointer_r8): Ditto.
    (c_f_pointer_r10): Ditto.
    (c_f_pointer_r16): Ditto.
    * iso_c_binding.c (c_f_pointer): Made C pointer parameter of type
    (void *).  Fixed whitespace and coding style.
    (c_f_pointer_u0): Ditto.
    (c_f_pointer_d0): Ditto.
    (c_f_procpointer): Ditto.
    (c_associated_1): Ditto.  Converted return type to void *.
    (c_associated_2): Ditto.
    (c_loc): Ditto.
    (c_funloc): Ditto.
    * iso_c_binding.h: Updated prototypes.
