[boost] Boost.Signals and BOOST_FUNCTION_NO_DEPRECATED

Hi Doug and all,

I have just tried adding signals to an existing project, using "Compatible Syntax", since the code has to compile on Borland and VC7.

The result was a link time error message complaining about a missing implementation for signal_base_impl constructor, and it took me several hours to work out that it was 
because BOOST_FUNCTION_NO_DEPRECATED was defined. The project defined BOOST_FUNCTION_NO_DEPRECATED at some point in the dim and distant past (probably as a check when it was 
added to Boost.Function).

Would it be possible to add something so that an informative error results in this case (or at least a compile time error)?  It might save others some hunting.

Regards,
Hugo
