#5231: Unncessary forward declaration of std::pair
------------------------------+---------------------------------------------
 Reporter:  chrisj            |       Owner:  djowel 
     Type:  Patches           |      Status:  new    
Milestone:  To Be Determined  |   Component:  fusion 
  Version:  Boost 1.45.0      |    Severity:  Problem
 Keywords:                    |  
------------------------------+---------------------------------------------
 fusion/adapted/std_pair.hpp contains a forward declaration of std::pair.
 This upsets libc++.

 However, <utility> is also (I believe) always included anywhere (at least,
 in every test I did), so the forward declaration isn't very useful anyway.
 This patch just replaces it with a #include <utility>. For me, this very
 slightly decreases the size of the pre-processed file on both mac and
 linux g++.
