[boost] Variant size bug?

Hello,
I just started experimenting with variant and ran into the following unexpected behaviour:

int main() {
  typedef boost::variant<> Var0;
  typedef boost::variant<int> Var1;
  typedef boost::variant<int,float> Var2;
  typedef boost::variant<int,float,bool> Var3;
  int s0 = boost::mpl::size<Var0::types>::type::value;
  int s1 = boost::mpl::size<Var1::types>::type::value;
  int s2 = boost::mpl::size<Var2::types>::type::value;
  int s3 = boost::mpl::size<Var3::types>::type::value;
  std::cout << s0 << ',' << s1 << ',' << s2 << ',' << s3 << std::endl;
}

>From this I expected the output:
0,1,2,3

but I got:
1,1,2,3

I'm runing the latest CVS version.
