+ * benchtests/bench-strcpy_chk.c: Move test-skeleton.c to top.
+ (test_main): Replace code with set_fortify_handler call.
+ * debug/test-strcpy_chk.c: Likewise.
+ * debug/tst-chk1.c: Likewise.
+ * debug/tst-longjmp_chk.c: Likewise.
+ * test-skeleton.c: Include fcntl.h & paths.h
+ (set_fortify_handler): Define.
