    * include/cln/object.h (cl_combine): define additional signatures, if
          HAVE_LONGLONG is defined, in order to keep the compiler happy.

        * src/integer/gcd/cl_I_gcd_aux2.cc (floorDD): fixed algorithmic bug
          that turned up when intDsize==32 and cl_word_size==64.
        * src/float/dfloat/elem/cl_DF_div.cc (operator/): fixed a missing cast
          to uint64 that turned up when intDsize==32 and cl_word_size==64.
