I do not know where you would expect to find signal.hpp but do not many 
libraries place their main header file directly in the boost directory ?

Both visit_each.hpp and last_value.hpp seem to have been put directly in 
the boost directory because they may be used by other implementations, 
even if currently they may be only used by signals.
