! rename a couple of the symbols from iso_c_binding. the compiler
! needs to be able to recognize the derived types with names different
! from the one in iso_c_binding because it will look up the derived types
! to define the args and return values of some of the procedures in
! iso_c_binding. this should verify that this functionality works.
