#2669: Boost 1.37 breaks spirit iterator differencing
-------------------------------------------+--------------------------------
 Reporter:  S Roderick <kiwi.net_at_[hidden]>  |       Owner:  djowel 
     Type:  Bugs                           |      Status:  new    
Milestone:  Boost 1.38.0                   |   Component:  spirit 
  Version:  Boost 1.37.0                   |    Severity:  Problem
 Keywords:                                 |  
-------------------------------------------+--------------------------------
 Attached minimal test file compiles fine under Boost v1.35, but fails to
 compile with Boost v1.37 (from Macports) and Darwin gcc 4.0.1. The problem
 has also been noted on other OS's with our software.

 The commented out `iterator_difference` attempt fails in the same manner
 with v1.37.
