Even if g++ 6.3.0-2 with `-std=c++11`, there is no problem if cygwin-devel-2.8.0-1 is installed. ``` $ uname -a CYGWIN_NT-10.0 inspiron5559 2.8.1(0.312/5/3) 2017-07-03 14:11 x86_64 Cygwin $ cygcheck -c cygwin-devel Cygwin Package Information Package Version Status cygwin-devel 2.8.0-1 OK $ g++ --version g++ (GCC) 6.3.0 Copyright (C) 2016 Free Software Foundation, Inc.
