I've not found anything in the build instructions that mentions that file
(or directory) specifically neither a mention of c++20.

The build instructions say that gcc 12 needs a c++11 compiler.

Apparently both gcc10 and clang 14 know enough about c++20 in c++11 mode
to compile the file but warn about the c++20 constructs.

That's why I'm asking.
