If I reduce the source further we get:
class Environment;
template<class T> struct ArrayCollection
{
  int insert(const T& theObj)
  {
    Environment::ReportError();
  }
};
struct Environment
{
  static void ReportError(void);
};

At the point were we call Environment::ReportError, Environment is not a complete class so we don't 
know what the functions are at this point.  If we had changed the template class ArrayCollection to a 
non template, we would get the error before 3.4.0 also because it needs to be defined before.

To fix your code, maybe move a header file includes around but I did not look into where the header 
files are.
