+ thrd tests: Add unit test for thrd_exit.
+ * tests/test-thrd_exit.c: New file, based on tests/test-thrd_create.c.
+ * modules/thrd-tests (Files): Add it.
+ (Makefile.am): Compile and run it.
+
thrd: On AIX 7.1 and 7.2, override also thrd_exit.
* lib/threads.in.h (thrd_exit): Consider REPLACE_THRD_EXIT.
* lib/thrd.c (rpl_thrd_exit): New function.
