when compiling code using boost::accumulators

A fix is already available upstream, see https://github.com/boostorg/accumulators/pull/54
but it is not included Debian's libboost1.74-dev package. Would you please apply this patch
in the packaging?

FWIW, I also reported this bug on Debian's BTS using reportbug. see
