There is a shorter sequence:
g++ -std=c++20 -fmodules-ts -x c++-system-header typeindex
g++ -std=c++20 -fmodules-ts -x c++-system-header stop_token
g++ -std=c++20 -fmodules-ts -x c++-system-header optional
g++ -std=c++20 -fmodules-ts -x c++-system-header system_error
g++ -std=c++20 -fmodules-ts -x c++-system-header streambuf
g++ -std=c++20 -fmodules-ts -x c++-system-header exception
g++ -std=c++20 -fmodules-ts -x c++-system-header unordered_map
g++ -std=c++20 -fmodules-ts -x c++-system-header complex
