+#warning
+#warning If code linked with this library includes Windows threads that
+#warning explicitly interact with POSIX threads, i.e. by calling POSIX API
+#warning routines, then those threads will acquire POSIX resources and
+#warning should call pthread_win32_thread_detach_np() on thread exit (see
+#warning README.NONPORTABLE), especially if the linked code depends on
+#warning reclaimed resources or the running of POSIX TSD destructors.
+#warning NOTE 1: Otherwise this will occur only when the process exits.
+#warning NOTE 2: Threads created via pthread_create() always auto-reclaim.
