It seems TryEnterCriticalSection only exists if you are compiling for 
windows NT 4 and later.  Probably the easiest thing for you to do is just 
delete the entire try_lock() method that uses TryEnterCriticalSection.  I 
only added it so signals2::mutex would fully implement the Lockable 
concept from Boost.Thread.  Signals2 doesn't actually use try_lock().
