CC_VERSION seems to be clang-15.0.0 for both SDK 13.3 and 14.4.

Running the following to get all predefined cpp macros:

cc -dM -E -x c /dev/null

The only difference in the output for 13.3 and 14.4 is

< #define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 130300
< #define __ENVIRONMENT_OS_VERSION_MIN_REQUIRED__ 130300
---
> #define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 140000
> #define __ENVIRONMENT_OS_VERSION_MIN_REQUIRED__ 140000

In either case, the output shows

#define __clang_version__ "15.0.0 (clang-1500.3.9.4)"

Am I missing something?
