------------------------------------------------+---------------------------
 The following code (relevant for a convenient thread-callback API) fails
 to compile with VC2010 due to a C2668 error:


 {{{
 typedef boost::function<void (int i)> fooCallback;
 typedef boost::function<void (int i, int k)> barCallback;

 void TestBF(fooCallback fc) {}
 void TestBF(barCallback bc) {}
 void MyFunc (int a, int b) {}

 int main(int argc, char **argv) {

     TestBF (&MyFunc);
     return 0;
 }
 }}}



 Without calling TestBF in main, everything is fine, there is no multiple
 definition error.
