warnings while boost bcp

[rgoyal@…]

I'm trying to use boost bcp for exporting lockfree/queue.hpp. The command seems to copy files over, but I am seeing the following warnings, and I am wondering are these harmful?

[ron@localhost boost_1_62_0]$ bin.v2/tools/bcp/gcc-4.8.5/release/link-static/bcp --namespace=boostts --boost=/home/ron/boost/include lockfree/queue.hpp /home/ron/TestApp
