 I think you should use it for 3.4.0 <= version <= 3.4.4 because I don't
get the warning neither wiht 3.4.5 nor 4.0.2. Unfortunately I don't have
3.4.4 any more to test with it.

 I didn't have any other problems.

 boost::function encapsulates any callable object, whether a function,
functor or bind-expression (which makes it also possible to apply it to
methods). It has a very nice syntax (at least if you use a conformant
compiler such as g++ 3 or MSVC 7.1+) and in general I think it's one of the
easiest to use of boost libraries but nevertheless a very useful one.
