I'm afraid this patch is responsible for an xterm full of warning messages
(even though it's just one warning ;-) ), when compiling the following
snippet with -W:

  #include <algorithm>
  #include <vector>

  using namespace std;

  typedef vector<bool> BOOLS;

  void f() {
    BOOLS v, w;

    copy(v.begin(),v.end(),inserter(w,w.end()));
    }
