[R-pkg-devel] Warning of DDRTree

[Xiaojie Qiu]

We are planning to update the DDRTree package but found the following
warnings:

  d:/RCompile/CRANpkg/lib/3.4/BH/include/boost/unordered/detail/buckets.hpp:586:29:
warning: ISO C++ 1998 does not support 'long long' [-Wlong-long]
  d:/RCompile/CRANpkg/lib/3.4/BH/include/boost/unordered/detail/buckets.hpp:591:38:
warning: ISO C++ 1998 does not support 'long long' [-Wlong-long]

 Those warnings seem to relate to boost but not to our package. Can anyone
have some idea on how to fix this?
The check log is here:
https://win-builder.r-project.org/incoming_pretest/170414_025235_DDRTree_015/00check.log
The windows install log is here:
https://win-builder.r-project.org/incoming_pretest/170414_025235_DDRTree_015/00install.out

Thanks in advance!

Best,
Xiaojie
