GCC 10 Adds Late Support For -std=c++20 To Target C++20

[pal666]

So if you want to rely on the full standard of C++20 you have to wait for C++20 to become the default.

i will use all features available in my compiler. half of c++20 is much better than none of c++20. and gcc10 includes more than half

Oof, "using enum" did not make it into gcc10's c++20 support.
