So it looks like all the code has to use ansi or arm, since I have a LOT
of stuff compiled in the arm mode, it would be better to build boost
using the "-sBUILD=<object-model>arm" switch, however now I'm back to
compile errors:

The problem here is that the name mangling scheme in the arm object model 
is limited and cannot express the full scope of ISO C++. That's why we have 
chosen to use the ansi object model as the default object model. A small 
isolated sample that works around the problem is:

---%<---
#include <iostream>
using namespace std;

template <typename T> void foo(T const &x)
{
   cout << "1" << endl;
}

template <typename T> void foo(T * const &x)
{
   cout << "2" << endl;
}

int main()
{
#ifdef __MODEL_ARM
   foo("abc");
#else
   foo("abc");
#endif
   return 0;
}
--->%---

This should get you going if you want to make boost 1.32.0 work with the 
arm object model.
