Attached is a prelimary replacement for function_traits.hpp. (When should I 
use the files section on yahoo? When should I attach? copy and paste code 
inline?)

I added specializations for member function pointers, and for those 
specializations, a typedef class_type which is the class type of the 
pointer. For no-PTS compilers I added a set of template functions for 
function pointers.

Unfortunely when I tried to test this by doing:
cout << boost::function<void (A::*)()>::arity << endl;
The following errors occured:
main.cpp: In instantiation of `boost::function_traits<void (A::*)()>':
main.cpp:33:   instantiated from here
main.cpp:33: base class `boost::detail::function_traits_helper<void 
(A::**)()>'
   has incomplete type
It looks like the add_pointer doesn't know what to do with member function 
pointers.

This may affect many things, so I didn't touch anything else :)

Would this affect boost::function? (from what I know it has some kind of 
member function pointer adaptor?)
