+<h1>Porting to GCC 15</h1>
+
+<p>
+The GCC 15 release series differs from previous GCC releases in
+<a href="changes.html">a number of ways</a>. Some of these are a result
+of bug fixing, and some old behaviors have been intentionally changed
+to support new standards, or relaxed in standards-conforming ways to
+facilitate compilation or run-time performance.
+</p>
+
+<p>
+Some of these changes are user visible and can cause grief when
+porting to GCC 15. This document is an effort to identify common issues
+and provide solutions. Let us know if you have suggestions for improvements!
+</p>
+
+<p>Note: GCC 15 has not been released yet, so this document is
+a work-in-progress.</p>

+
+<h3 id="header-dep-changes">Header dependency changes</h3>
+<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>
+<p>
+In particular, the following header is used less widely within libstdc++ and
+may need to be included explicitly when compiling with GCC 15:
+</p>
+<ul>
+<li> <code><cstdint></code>
+ (for <code>std::int8_t</code>, <code>std::int32_t</code> etc.)
+</li>
+</ul>
