Compilation failure with gcc/7.3.1 #14

Hello,

When I try to compile virtual casing on Amazon Linux 2 (derivative of CentOS 7) with the default gcc 7.3.1, I am getting errors.

The output is

I believe older versions of GCC are not fully compliant or don't fully support the C++11 standard. This code compiles with GCC-9 and newer versions.
