Extensions to binder library uploaded

Hi all,

I have been experimenting with the boost bind library, and in 
particular have modified it so that it passes arguments by value or 
reference as defined by the function's signature, so that ref() need 
not be used. 

Also, one can now pass temporaries as arguments.

This only works with functions and member functions for now- I have 
left function objects with their current by-value default argument 
passing semantics. (It could be extended to function objects either 
by binding a pointer to the operator() member function (which assumes 
a single non-overloaded operator() and, in any case, would require a 
typeof facility to implement transparently), or by requiring member 
argument types and arity in the function object).

I have found this new behaviour to be more useful and intuitive 
especially for mutating local functions which need pass-by-reference 
to accumulate results.

Anyway, I have uploaded the changed files in "bind_ext.zip" in case 
anyone else wants to experiment with this. (You will need Intel 5 to 
compile under Windows).
