+        Fix obscure porting bug with varargs functions.
+        The code assumed that int is treated like ptrdiff_t in a vararg
+        function, which is not a portable assumption.  There was a similar
+        -- though these days less likely -- porting problem with various
+        assumptions that pointers of different types all smell the same as
+        far as vararg functions is conserved.  To make this problem less
+        likely in the future, redo the API to use varargs functions.
+        * alloc.c (make_save_value): Remove this vararg function.
+        All uses changed to ...
+        (make_save_int_int_int, make_save_obj_obj_obj_obj)
+        (make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
+        New functions.
+        (make_save_ptr): Rename from make_save_pointer, for consistency with
+        the above.  Define only on platforms that need it.  All uses changed.
