Hi,

I had some compiling errors when I wanted to try out signals2. In 
predestructible.hpp line 33 there is an extra semicolon (the empty {} 
scope has a an extra ;). Also, in tracked_objects_visitor.hpp line 85, 
the "trackable" parameter is unused, which causes a warning.

The warning is not critical, but the error is. It basically forces one 
to either manually fix the predestructible.hpp header, or to stop using 
the -pedantic flag.

My flags: -Wextra -Wall -std=c++98 -pedantic
