main CVS snapshot of the current Boost.Signals
Started preparations to move out legacy code; does not compile.
Further work on moving out legacy code; still doesn't compile.
Finished moving out legacy code; compiles again; passes original tests.
Minor fixes; compiles now with BOOST_SIGNALS_NO_LEGACY_SUPPORT defined.
Made last_value throw when it can't generate a return value, instead
of it resulting in undefined behavior.  Made last_value<optional<T> >
return uninitialized optional instead of throwing.
inherit publically from runtime_error for no_slots_error.
Simplified the template interface; some code cleanup; added Allocator template parameter; work-in-progress;
*** empty log message ***
Updated tutorial to use new boost::track instead of old boost::trackable.
Updated faq wrt thread-safety.
Updated signalN reference to reflect changes for thread-safety.
Added ThreadingModel template parameter to signal reference documentation.
Made the test of an already auto-disconnected slot actually test
something (the slot was never connected to the signal).
Made slots throw bad_weak_ptr when called with expired tracked
objects.  Combiners now have to catch bad_weak_ptr exceptions
thrown on slot iterator dereference.  Tracking works automatically
now for slots that call other slots.
Throw more specific "expired_slot" exception, derived from bad_weak_ptr
when slot is called with an expired tracked object.
tweaked no_slots_error exception.
Patch from "Stjepan Rajko" <stipe@asu.edu> that fixes some
compile warnings and a compile error under MSVC.
