 class boost::serialization::extended_type_info generates warning
 [http://msdn.microsoft.com/en-us/library/wzxffy8c%28v=VS.90%29.aspx c4265]
 with visual studio 2005, 2008, and 2010 because the destructor is not
 virtual, even though the class has virtual functions.

 Looking at the class, I see that the warning was fixed only for gcc:
 {{{
     // account for bogus gcc warning
     #if defined(__GNUC__)
     virtual
     #endif
     ~extended_type_info();
 }}}
 I believe the fix is to always declare the destructor virtual.
