| To recap:

|   template<typename _Tp, typename _PoolTp>
|     class __mt_alloc : public _PoolTp
|     {
|     public:
| 
|       template<typename _Tp1, typename _PoolTp1 = _PoolTp>
|         struct rebind
|         { 
| #if 1
|           // ok with edg
| 	  typedef _PoolTp1::_M_rebind<_Tp1>::other pool_type;

This is wrong.  Missing infamous "::template" and "typename".

| #else
|           // as g++ suggests but cannot compile
|           typedef _PoolTp1::template _M_rebind<_Tp1>::other pool_type;

This is wron. Missing infamous "typename".

| #endif
| 	  typedef __mt_alloc<_Tp1, pool_type> other; 
| 	};
|     };
| 
| None of these work with g++. If I just keep on adding junk, say
| 
| 	  typedef typename _PoolTp1::template _M_rebind<_Tp1>::other pool_type;

This junk is correct standard way to write it
