These minor updates have been posted to the www.boost.org web site:

*  polymorphic_downcast<> in the utility library cast.hpp header now
works for multiple inheritance cases.
 
*  shared_ptr<> and shared_array<> swap() functions added in the
smart pointer library.
 
*  timer.hpp elapsed_max() and elapsed_min() functions added to the
timer library.
 
*  integer library bin_ubin.hpp changes to eliminate compiler warning
messages.
 
*  config.hpp minor change (BOOST_DECL) to aid library developers.
No impact on library users.
