Re: [boost] Review Request: Dataflow.Signals

I tried MSVC8 and was able to go small steps forward. Basically, I was
able to compile all header files, albeit explicitely setting /Zm1000.
Which is fine with me but might be helpful to know for other people.

Where I get into troubles is when defining the data processor class.
For demonstration purposes I just create an empty class for now. But I
have the same errors when I copy and paste your processor from the
documentation.

class processor : public signals::filter<processor, void (double)> {};

Here is what my compiles outputs:

1>c:\boost\boost\type_traits\function_traits.hpp(170) : error C2504:
'boost::detail::function_traits_helper<Function>' : base class
undefined

This time I'm using MSVC 8 with the updated boost trunk.

BTW, why to have your own boost/functional lib? Are you overriding or
extending it?
