“If you ever try to relocate a binary that doesn't work with the default configuration, the --detect option is a good first thing to try.”

So why does that work?
{"clang", nullptr}
{"clang++", "--driver-mode=g++"}
{"clang-c++", "--driver-mode=g++"}
{"clang-cc", nullptr}
{"clang-cpp", "--driver-mode=cpp"}
{"clang-g++", "--driver-mode=g++"}
{"clang-gcc", nullptr}
{"clang-cl", "--driver-mode=cl"}
{"cc", nullptr}
{"cpp", "--driver-mode=cpp"}
{"cl", "--driver-mode=cl"}
{"++", "--driver-mode=g++"}
{"flang", "--driver-mode=flang"}
It works by chance...

TIL: if you symlink ++ -> clang it works as a compiler in C++ mode.
Note that this is only about the compiler driver mode, i.e. the default libraries, search paths, include directories, etc. The source language is determined by the file extension unless specified with e.g. `-x c++`.
