As far as Arm GNU Toolchain it is up to 15.2.1 and CMake and make built all the pico_w examples fine FWIW. Maybe the issue has been resolved, but more testing is always recommended I suppose.
Full disclosure, my particular versions are as follows; Pico C SDK 2.2.0, cmake 3.24.1, arm-none-eabi-gcc 15.2.1, gcc 11.2.0, make 4.3
