+Subject: [PATCH] build: Define _GNU_SOURCE for pthread_getname_np
+
+With clang-16, implicit function definitions are treated as errors. As a
+result, the check for pthread_getname_np fails because
+pthread_getname_np is only provided under _GNU_SOURCE (see
+pthread_getname_np(3))
+
+> Checking if "pthread_getname_np" : links: NO
+
+The compilation failure is
+
+> error: implicit declaration of function 'pthread_getname_np' [-Werror,-Wimplicit-function-declaration]
+
+The inclusion of pthread.h lib/rb-debug.c must be moved above the system
+headers because they may include pthread.h themselves (and in practice
+unistd.h does). If that change is not done, lib/rb-debug.c will fail to
+compile for the same reason as the configure test.
+
+Note that to test this, one must disable prctl() detection.
