Phoronix: LLVM Clang Now Exposes -std=c++23 Rather Than -std=c++2b

Merged today to LLVM 17 Git is now recognizing -std=c++23 rather than just -std=c++2b for the Clang compiler now that C++23 has been deemed technically complete...

GCC 11 also opted to go straight for -std=c++23, though it also supports -std=c++2b.

Looking at the clang commit, it appears that -std=c++2b no longer works, so existing builds would fail until compilation flags are updated. With GCC you can continuing using -std=c++2b even though its meaning is identical to -std=c++23.
