You might want to change the Makefile defaults using CFLAGS=-O0 ./configure 
but I don't think you can omit those flags. I think they are used to allow 
in-kernel Click.

This is a basic C++ problem. In your headers use forward declarations of your 
classes combined with include guards. 
You should get something like this in e.g. BasicFlowGraph.hh:
#ifndef ...
#define ...

class Edge;
class EndPoint;
class BasicFlowgraph{
...
}
#include "Edge.hh"
#include "EndPoint.hh"
#endif

Then everything can be compiled in any order.
