Hi,
I'm getting link errors with libstdc++.  At first I thought I must have 
been missing a package, but AFAICS I have all the relevant ones.  I 
assumed libstdc++ would be linked in by default from a g++ command line. 
  I couldn't see anything similar mentioned in the archives.  I assume 
c++ wouldn't be broken by default for the whole distribution like this, 
what have I forgotten (and out of interest, why does the 3.3.1 version 
of gcc and g++ use the 3.2.3 specs)?

scarff-box ~ $ cat nolink.cc

#include <iostream>

using namespace std;

int
main(int, char**)
{
   cout << "hello.";
}
