Thanks to you doc:
libstdc++: [_GLIBCXX_DEBUG] Define __[glibcxx,cpp_lib]_null_iterators
_GLIBCXX_DEBUG has now fully N3344 compliant iterator checks, we
can define
__glibcxx_null_iterators and __cpp_lib_null_iterators macros like
the normal
mode.
libstdc++-v3/ChangeLog:
* version.def (null_iterators): Remove extra_cond.
* version.h: Regenerate.
Ok to commit ?
I already noticed that GCC 13 has no version.h file so no backport question.

Both committed now.
Just to confirm, those 2 last patches should be backported to gcc-13
branch, right ?
Yes please.
I might have a try to update version.h but if you want to do it before
don't hesitate.
You'll need to have 'autogen' installed to do it (I'm going to update
the docs to describe that today).
I've documented it in a new "Generated files" section at the end of
