3410	"Warnings in Boost::function when compiled with ""-Wold-style-cast"""	c-rom ( -at- ) gmx . de	Douglas Gregor	"Boost::function reports warnings when compiled with ""-Wold-style-cast"".

There are several old style casts left (besides many ""new style casts"", so this might be harmonized)
in files:

boost/function/function_base.hpp

boost/function/function_template.hpp

Please see ticket #2983 which is very similar to this one.

The following code example reproduces the issue with Boost 1.40:

Example.cpp

%<-------------------------------------

#include <iostream>

#include <boost/function.hpp>


struct add

{

  int operator()( int arg1, int arg2 )

  {

    return ( arg1 + arg2 );

  }

};

int main( int argc, char** argv )

{

  boost::function<int ( int, int )> f;

  f = add();

  std::cout << f( 2, 2 ) << std::endl;

  return 0;

}
