+Subject: [PATCH] libunwind: guard unreachable() macro to avoid redefinition
+ with stddef.h
+
+The build fails due to a macro redefinition conflict for `unreachable()`.
+GCC 15.2.0 defines `unreachable()` in `stddef.h`, and `libunwind_i.h` also
+defines it based on the presence of `HAVE__BUILTIN_UNREACHABLE`. This causes
+a redefinition error when building with `-Werror`.
+
+Added a guard around the `unreachable()` macro definition in `libunwind_i.h`
+to ensure it is only defined if not already present.
+
+Upstream-Status: Pending
+
