Compile using "clang++ -std=c++20"
Comparing two objects of a class or strut using <, >, <=, or >= results in the
warning "zero as null pointer constant" if the class has a defaulted
operator<=> (either friend or member).
To reproduce, compile the attached file with "clang++ -std=c++20"
Tested on Ubuntu 20.04 on WSL, using clang-11 package from
<a href="http://apt.llvm.org/focal/">http://apt.llvm.org/focal/</a>:
