* Makerules (sysd-rules): Define PTW for ptw-* files.
* Versions: Define GLIBC_2.7 for libc. * include/stdio.h: Declare __fortify_fail. * debug/fortify_fail.c: New file. * debug/Makefile (routines): Add fortify_fail. * debug/chk_fail.c: Use __fortify_fail. * debug/stack_chk_fail.c: Likewise. * io/Versions: Export __open_2, __open64_2, __openat_2, and __openat64_2 for GLIBC_2.7. * io/fcntl.h: When compiling with fortification, include bits/fcntl2.h. * io/open.c: Define *_2 variant of function which checks for O_CREAT and fails if necessary. * io/open64.c: Likewise. * io/openat.c: Likewise. * io/openat64.c: Likewise. * sysdeps/unix/sysv/linux/open64.c: Likewise. * sysdeps/unix/sysv/linux/openat.c: Likewise. * sysdeps/unix/sysv/linux/openat64.c: Likewise. * io/bits/fcntl2.h: New file. * include/fcntl.h: Declare __open_2, __open64_2, __openat_2, and __openat64_2. * include/bits/fcntl2.h: New file. * sysdeps/unix/sysv/linux/Makefile [subdir=io] (sysdep_routines): Add open_2. * sysdeps/unix/sysv/linux/open_2.c: New file.
