Hi,

this is using boost 1.42, I think the same happens in 1.43

Using boost::accumulators generates a compiler warning in 
boost/concept_check.hpp:335. it seems the Arg member is a reference, 
but gcc doesnt like that there is no way to initialize it since it is 
private and the class does not have a constructor. this is particularly 
annoying since due to metaprogramming and the lag of variadic templates 
the instantiation trace in the error message for a single error is a 
few pages long, and it comes each time I instantiate an accumulator. is 
there a way to avoid this?

Best

Daniel
