 Hello,
 I'm trying to use accumulators to compute the mean of a set of double.
 Firstly, I instantiate an accumulator_set object using the correct tag, as
 following :

 #include <boost/accumulators/accumulators.hpp>
 #include <boost/accumulators/statistics.hpp>

 typedef boost::accumulators::accumulator_set<double,
 boost::accumulators::stats< boost::accumulators::tag::mean > >
 accumulator_type;

 accumulator_type acc;

 I try to compile this code with clang and with gcc(4.6), and both of them
 give the same kind of error :

 With clang :
 /usr/include/boost/accumulators/statistics/mean.hpp:42:48: error: too many
 arguments provided to function-like macro invocation return
 numeric::average(sum(args), count(args));

 With gcc :
 /usr/include/boost/accumulators/statistics/mean.hpp:42:59: error: macro
 "average" passed 2 arguments, but takes just 1
