Hi,

I'm using Boost.Serialization for my project and have run into a cryptic 
warning message. Although it doesn't seem to actually do any harm on 
run-time I would like to know what it means, and possibly how I can fix 
it without #pragma disabling it.

The relevant code and the entire warning can be found here:
Codepad paste <http://codepad.org/MVx2O6dC>

The error message was produced by Visual Studio 2008.

Since I'm not perfectly sure what the correct syntax is supposed to be 
regarding lines 74 and 75 when dealing with classes using multiple 
inheritance and since I couldn't find documentation regarding the 
subject those could very well be the source of my problems (although it 
seems to do what it is expected to do).

All help greatly appreciated, thanks in advance.
