* I'm calling this as `AX_CXX_COMPILE_STDCXX_20([noext])`, just like the C++17
macro.
* Just the same as the other C++ standard version detection macros, but
there's a C++20 standard now.
* I guess the license is the same as `m4/ax_cxx_compile_stdcxx_17.m4`?  I just
copied that and s/17/20/.
* The sources are attached as a patch, they're also up on my github
<https://github.com/palmer-dabbelt/autoconf-archive/commit/42a4d05f263e579dbd5fc5435125847bc6a1d8c9>.

I tested this with my local GCC and it results in `g++ -std=c++20 `, but
that's about all I tried.
