-static still required for me

Cool, your patch almost does it for me as well.  I used to get reams
of hard to read template-laden errors involving wchar in addition to
the undefined reference to `__atan2' unless I used -static.  I think
the remaining issue is FreeBSD specific.

#include <iostream>
using namespace std;

int main() {
  cout<<"hi"<<endl;

  return 0;
}
