Use --g++ (or --gnu_version 140200 to emulate a specific GCC version)

--strict_gnu and --no_strict_gnu can then be used to switch between
-std=c++xx and -std=gnu++xx for GCC.

So to emulate gcc 14.2 with -std=c++20 you would use --c++20
--gnu_version 140200 --strict_gnu

Similarly, to emulate clang 18.1.0 with --std=c++20 you would use
--c++20 --clang_version 180100 --strict_gnu
