GCC output with -v

-lstdc++fs switch not working on gcc 5.3.0-RC-20151130

I've tried building code example from here:
http://en.cppreference.com/w/cpp/experimental/fs/directory_iterator

with this command line:
/opt/gcc53/bin/g++ -v -std=c++1z  -lstdc++fs -L/opt/gcc53/lib64 test.cpp

And I'm getting errors that are in attached output.txt

Using nm on libstdc++fs.a show that those symbols are there, so it looks like
gcc problem.
