+        * include/cln/object.h (cl_combine): define additional signatures, if

+        * src/base/cl_low.h (logcount_64): ...for this macro.
+        * src/base/random/cl_UL_random.cc (random32): if HAVE_DD a is an ULL.
+        * 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
