here is the patch with consistent __USE_XOPEN2K8

ok to commit?

2015-05-21  Szabolcs Nagy  <szabolcs.nagy@arm.com>

	[BZ #18234]
	* conform/data/sys/stat.h-data (struct stat): Add tests for st_atim,
	st_mtim and st_ctim members.

	* sysdeps/nacl/bits/stat.h (struct stat, struct stat64): Make
	st_atim, st_ctim, st_mtim visible under __USE_XOPEN2K8 only.

	* sysdeps/unix/sysv/linux/generic/bits/stat.h (struct stat,):
	(struct stat64): Likewise.

	* sysdeps/unix/sysv/linux/ia64/bits/stat.h (struct stat,):
	(struct stat64): Likewise.

	* sysdeps/unix/sysv/linux/microblaze/bits/stat.h (struct stat,):
	(struct stat64): Likewise.
