+  <p>GCC has experimental support for the next revision of the C++
+  standard, which is expected to be published in 2023.</p>
+
+  <p>C++23 features are available since GCC 11. To enable C++23
+      support, add the command-line parameter <code>-std=c++2b</code>
+      to your <code>g++</code> command line. Or, to enable GNU
+      extensions in addition to C++23 features,
+    add <code>-std=gnu++2b</code>.</p>
+
+  <p><strong>Important</strong>: Because the ISO C++23 standard is still
+    evolving, GCC's support is <strong>experimental</strong>.  No attempt will
+    be made to maintain backward compatibility with implementations of C++23
+    features that do not reflect the final standard.</p>
