Re: [boost] [thread_safe_signals] returning void from last_value when possible

Hello,

When dealing with a signature of void return type, the Boost.Signals version of last_value only returns last_value::unusable when the compiler doesn't support void returns: http://svn.boost.org/trac/boost/browser/trunk/boost/last_value.hpp#L34

But the thread-safe version always returns last_value::unusable: http://svn.boost.org/trac/boost/browser/sandbox/thread_safe_signals/boos t/last_value.hpp#L68

Could the thread-safe version be made consistent with Boost.Signals?

Ok, I've done it in svn. By the way, did you mean to make struct unusable private in boost.signals last_value<void>? Because it's declared as a struct so it is actually public.
