[Boost-users] [range, iterator?] compiler error going from 1.34 to 1.37

We are upgrading our legacy code to use boost 1.37 from version 1.34 and have hit a slight hitch. The following (massively simplified) code no longer compiles. I tried it on more than one compiler and the error messages aren't too useful in helping to determine the issue. (The target compiler will be VS 2k8). Any assistance would be appreciated.

                                Thanks in advance.
