 Boost::exception reports warnings when compiled with "-Wold-style-cast".

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

 The following code example reproduces the issue with Boost 1.40:

 {{{
 #include <iostream>
 #include <boost/exception.hpp>

 typedef boost::error_info<struct tag_my_info,int> my_info;

 struct my_error: virtual boost::exception, virtual std::exception { };

 void f()
 {
   throw my_error() << my_info(42);
 }

 void g()
 {
   try
   {
     f();
   }
   catch( my_error & x )
   {
     if( int const * mi=boost::get_error_info<my_info>(x) )
       std::cerr << "My info: " << *mi;
   }
 }
 }}}

 The piece of code for this bug report has been compiled with g++ (GCC)
 3.4.3:[[BR]]
