C++23 is fast approaching. Is there any clue when vsi Clang will catch up to the standard?

There is the compiler piece and the library piece.
For the compiler itself, I would like to refresh to a newer clang/LLVM (hopefully clang 16 or higher) later this year, but nothing to promise yet.
It is usually the RTLs that need the real work. For example, we don't even do all the C++17 libraries yet.
For those who care, here's the clang C++ status page

wonder why I only just now saw this when I've been active in the forum all week. Anyways, it also requires a complete C library to stand on. Is the c compiler (cc) also clang?

The C compiler is still DEC C. DEC C has a bunch of extensions which a lot of VMS code relies on.

Does the clang compiler rely on the Dec C (C Standard) library or does it rely on its own?
Though yes I'm aware there is a variety of Posix in the Dec C library. Let me see, in order to be C99 compliant I have to include <complex.h> before <math.h>
I could go through and check to ensure every library has everything the standard should have. As for libraries Dec C is not 100% C99 compliant, it lacks <fenv.h>. There are no libaries from C11 or C23. Although some of those libraries could be written in part to full without all compiler features. threads.h could be defined as an interface over the posix like threads.
