+Subject: [PATCH] index-pack: rename struct thread_local
+
+"thread_local" is a keyword in C23.  To make sure that our code compiles
+on a wide variety of C versions, rename struct thread_local to "struct
+thread_local_data" to avoid a conflict.

+Subject: [PATCH] reflog: rename unreachable
+
+In C23, "unreachable" is a macro that invokes undefined behavior if it
+is invoked.  To make sure that our code compiles on a variety of C
+versions, rename unreachable to "is_unreachable".
