Please I also have an issue with that line.
CC=clang-9 CFLAGS='-DREUSEPORT_OPT=1 -Wno-deprecated-declarations' ./configure && make

I'm using kernel version 6.2
I have tried with available versions of clang on ubuntu 23.04 (clang-13, clang-14, clang-15) but I still seeing erros

This is the log of the terminal :
