Hi !

I've started to use Boost.Accumulators and I'm getting tons of ugly warnings 
when compiling with optimization on. See full "warn.log" for details,
This boils down to boost/concept_check.hpp 

335: warning: non-static reference ‘const float& 
boost::UnaryFunction<boost::numeric::functional::as_max<const float, void>, 
float, const float&>::arg’ in class without a constructor [-Wuninitialized]

when the check ist called with a reference parameter.
It seems that providing a dummy constructor is sufficient to silence this.
Please find a patch attached.

Okay to commit ?

Or are the better ideas ?

Yours,

Jürgen
