#5450: range doesn't support circular_buffer

Milestone:  To Be Determined  |   Component:  range

------------------------------+---------------------------------------------
 The range library doesn't seem to specialise for circular_buffer.

 Code bellow should fix the problem.

 It must be placed `some where' i.e. in `circular_buffer' path.
