+Subject: Revert broken part of commit 5b0d43b767bf3f800f97892905b6d1ba50150f1a
+
+This commit breaks AX_CXX_COMPILE_STDCXX noext/ext option handling, which
+caused
+"AX_CXX_COMPILE_STDCXX(20, [noext], [optional])"
+to result in
+"checking whether g++ supports C++20 features with -std=gnu++20... yes"
+which is not the desired outcome when using "noext".
+It should check for "-std=c++20" instead for "-std=gnu++20", as it did before.
+
+See
+<https://github.com/autoconf-archive/autoconf-archive/pull/300#issuecomment-2416443298>
+and
