Remove check for stdarg.h (HAVE_STDARG_PROTOTYPES) in configure.ac #93207
Description
CPython checks for stdarg.h as HAVE_STDARG_PROTOTYPES 1 at some places 2 but not at other places 3. Either this check should be repeated at every call site or should be removed all together, most compilers supports this nowadays (should be verified with buildbots).

Bit late, but JFYI, this paper got accepted into C23.
Edit: sorry for the double-post; GH bugging with server errors here...
