#5901: Suppressing warnings from Cray compiler
------------------------------+---------------------------------------------
 Reporter:  johnmaddock       |       Owner:  eric_niebler
     Type:  Bugs              |      Status:  new         
Milestone:  To Be Determined  |   Component:  proto       
  Version:  Boost 1.47.0      |    Severity:  Problem     
 Keywords:                    |  
------------------------------+---------------------------------------------
