1043	last_value<void>::result_type set to last_value<void>::unusable when it could be set to void	Stjepan Rajko	Stjepan Rajko	"Currently, last_value<void>::result_type is set to last_value<void>::unusable.  On compilers which support void returns, it seems like it would be more beneficial to set it to void instead.  I.e.,

  template<>
  struct last_value<void> {
#ifdef BOOST_NO_VOID_RETURNS
    struct unusable {};

  public:
    typedef unusable result_type;
#else
  public:
    typedef void result_type;
#endif // BOOST_NO_VOID_RETURNS

...

Patch attached.
