boost.bind and g++ 2.95.3 woes

Hi there,

I have a problem compiling the following code
with g++ 2.95.3 and boost 1.28.0.

---%<---
#include <boost/bind.hpp>
#include <boost/function/function0.hpp>

struct A
{
        A(boost::function0<void> const &) { }
};

void foo(boost::function0<void> const &) {}
void bar(unsigned int) {}

int main(int argc, char *argv[])
{
        boost::bind(foo, boost::bind(bar, 0)); // ok
        A a1(boost::bind(bar, 0)); // ok
        A a2(boost::bind(foo, boost::bind(bar, 0))); // error
        return 0;
}
--->%---

The line marked with error gives me a whole flood of
error messages. Is this a problem with my version of
gcc? Or am I doing a stupid mistake?

TIA, Markus

PS: Here are the errors I get:
