+Subject: [PATCH] configure: fix tls detection
+
+Configure TLS detection tests were failing because of wrong usage of
+pthread_create(). Problem was caused by wrong definition of thread
+functions which require void *f(void *) instead of int f(void *) or
+void f(void *).

+Subject: [PATCH] configure: Fix return values in start thread routines
+
+Thread start routines must return a void * value, and future
+compilers refuse to convert integers to pointers with just a warning
+(the virtualtimer probe).  Without this change, the probe always fails
+to compile with future compilers (such as GCC 14).
+
+For the tls probe, return a null pointer for future-proofing, although
+current and upcoming C compilers do not treat this omission as an
+error.
+
+Updates commit dd11311aadbd06ab6c76d ("configure: fix tls detection").
