Debian 12/Python 3.11

I tried building this on (Bookworm/Debian 12) which comes with gcc 12.2.0

cc -O2 -Werror -g -fPIC -fno-strict-aliasing -Wall -I/usr/lib/gcc/aarch64-linux-gnu/12/plugin/include -I/usr/lib/gcc/aarch64-linux-gnu/12/plugin/include/c-family -I.  -c -x c++ -fno-rtti -o gcc-declaration.o -I./ gcc-declaration.c
gcc-declaration.c: In function 'bool gcc_decl_is_builtin(gcc_decl)':
gcc-declaration.c:44:10: error: 'DECL_IS_BUILTIN' was not declared in this scope; did you mean 'DEF_LIB_BUILTIN'?
   44 |   return DECL_IS_BUILTIN (decl.inner);
      |          ^~~~~~~~~~~~~~~
      |          DEF_LIB_BUILTIN
make: *** [Makefile:98: gcc-declaration.o] Error 1

Looking around it looks like gcc10 changed the macros and a new feature __has_builtin replaces the 'DECL_IS_BUILTIN' macro:

The special operator __has_builtin (operand) may be used in constant integer contexts and in preprocessor ?#if? and ?#elif? expressions to test whether the symbol named by its operand is recognised as a built-in function by GCC in the current language and conformance mode.

Unfortunately just replacing

  return DEC_IS_BUILTIN (decl.inner);

with
return __has_builtin (decl.inner);

fails to deal with dec.inner, and there I am a bit stuck.

Thanks for looking
