+<p>Some C++ Standard Library headers have been changed to no longer include
+other headers that were being used internally by the library.
+As such, C++ programs that used standard library components without
+including the right headers will no longer compile.

+<p>
+The following headers are used less widely in libstdc++ and may need to
+be included explicitly when compiled with GCC 13:

+<li> <code>&lt;cstdint&gt;</code>
+  (for <code>std::int8_t</code>, <code>std::int32_t</code> etc.)
