compile error when combining headers

[pcaspers]

I am using 1_66. I have two header files in two different libraries which work fine on their own, but when including both headers at once I get a compile error (with clang and msvc). A small example is given by the following code

test.cpp:

// first header file

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

/* ... */

typedef boost::accumulators::accumulator_set<
    double, boost::accumulators::stats<boost::accumulators::tag::weighted_kurtosis>, double>
    accumulator_set;
accumulator_set acc_;

/* ... */

// second header file

#include <boost/accumulators/statistics.hpp>

/* ... */

Compiling this code with clang++ -c test.cpp yields
