    C++20 features are available since GCC 8.

    To enable C++20 support, add the command-line parameter

    -std=c++20

    For G++ 9 and earlier use

    -std=c++2a

    Or, to enable GNU extensions in addition to C++20 features, add

    -std=gnu++20

    Thanks. That was very helpful.

    My system complains about -std=c++20 so I cannot test it. (I think
    I'll wait for a native C release.)

    That will be a while. It's not hard to build current GCC from scratch
    on a Linux system.

    I doubt that. I wouldn't have the first clue about how to do it, and I'm certainly no Linux newbie.

    Maybe it (getting/building GCC) should be part of your "bootstrap" script?

    Also, is there an easy way to find out if your current GCC is "good enough" ?

    The system I am typing this on says it has GCC 9.4? Will that work?
