//inversion of the problem :)
struct base_exception : public std::exception
{
    std::list snowball;

    base_exception() { }
    void add(base_exception* e) { snowball.push_back(e); }
};

void func2()
{
    func2_exception e;
    e.add(new func2_exception());
    throw e;
}

void func1()
{
    try
    {
        func2();
    }
    catch(base_exception& e)
    {
        e.add(new func1_exception());
        throw e; 
    }
}
int main(void)
{
    try
    {
        func1();
    }
    catch(base_exception& e)
    {
        std::cout << "Got exception" << std::endl;
        //print info in the direct order of exceptions occurence
        foreach(base_exception* exception, e.snowball)
        {
              std::cout << exception->what();
              std::cout << "next exception was:" << std::endl;
        }
    }
}

hmmmm...
