Thank you for your information.
If I understand correctly, there is three workaround solutions.
. Use g++ option `-std=gnu++11` instead of `-std=c++11`

I've tried this. It works fine.
. Downgrade `cygwin-devel` to 2.8.0-1 instead of 2.8.1-1.

Of course, it works fine in my environment.
. Use gcc-6.3.0-2 instead of gcc-5.4.0-1
You reported in
https://cygwin.com/ml/cygwin/2017-07/msg00109.html
I'd like to try this.
Thanks
