Next gcc46 Problem

[Johannes Ruscheinski]

After finally successfully installing gcc46 and compiling a tiny test
program with

gcc-mp-4.6 -std=gnu++0x AutoTest.cc

I get:

Undefined symbols:
  "std::ios_base::Init::Init()", referenced from:
      __static_initialization_and_destruction_0(int, int) in ccyAO1Lq.o
  "std::ios_base::Init::~Init()", referenced from:

  "std::cout", referenced from:
      _main in ccyAO1Lq.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

How can I resolve this?
