+Porting to GCC 15
+
+
+The GCC 15 release series differs from previous GCC releases in
+a number of ways. 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.
+
+
+
+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!
+
+
+Note: GCC 15 has not been released yet, so this document is
+a work-in-progress.

+C++ language issues
+
+Header dependency changes
+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.
+
+
+In particular, the following header is used less widely within libstdc++ and
+may need to be included explicitly when compiling with GCC 15:
+
+
+
+ (for std::int8_t, std::int32_t etc.)
