+ * rpcsvc/nislib.h: Include rpcsvc/nis.h.
+ * sysdeps/unix/sysv/linux/netrose/rose.h:
+ Include sys/socket.h and netax25/ax25.h.
+
+ * inet/netinet/icmp6.h, inet/netinet/ip6.h
+ * resolv/arpa/nameser_compat.h:
+ Use __BYTE_ORDER etc. instead of BYTE_ORDER etc.
+
+ * sysdeps/unix/sysv/linux/sys/quota.h:
+ Use __caddr_t instead of caddr_t.
+ * sysdeps/unix/sysv/linux/sys/timerfd.h:
+ Use __clockid_t instead of clockid_t.
+
+ * sysvipc/sys/ipc.h: Remove unnecessary #warning.
+
+ * argp/argp.h: Check whether _LIBC is defined before expanding it.
+ * posix/glob.h: Check whether __USE_XOPEN2K8 is defined instead of
+ expanding it.
+
+ * misc/sys/cdefs.h: Tidy up conditional nest defining __flexarr.
+ Define __glibc_c99_flexarr_available to 1 when the compiler
+ supports C99-compatible flexible array members, 0 otherwise.
+ * sysdeps/unix/sysv/linux/bits/socket.h
+ * sysdeps/mach/hurd/bits/socket.h
+ * bits/socket.h: Use __glibc_c99_flexarr_available in
+ definitions of struct cmsghdr and CMSG_DATA.
