2669	Boost 1.37 breaks spirit iterator differencing	S Roderick <kiwi.net@…>	Joel de Guzman	"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.
