Comment (by kencu):

 Ryan is right, -latomic should not be needed. He found the script bit that
 tests for it, I modified it very slightly, and every time I run this
 script on Intel Ventura, it says "-latomic linker flag not needed."

 Can I ask what you see?

 {{{
 #!/bin/sh

 echo "Running configure script"

 # Find compiler
 CC=clang++-mp-14

 # Detect whether -latomic is needed during linking. This is needed on some
 # platforms, notably ARM (Raspberry Pi).
 echo "#include <stdint.h>
 uint64_t v;
 int main() {
     return (int)__atomic_load_n(&v, __ATOMIC_ACQUIRE);
 }" | ${CC} -x c -

 if [ $? -eq 0 ]; then
   echo "-latomic linker flag not needed."
 else
   echo "-latomic linker flag needed."
   EXTRA_PKG_LIBS=-latomic
 fi


 # Success
 exit 0
 }}}
