http://sourceware.org/ml/libc-alpha/2005-02/msg00122.html

2005-02-26  GOTO Masanori  <gotom@debian.or.jp>

	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_STAT64_SYSCALL.
	* sysdeps/unix/sysv/linux/alpha/fxstat.c: Check
	__ASSUME_STAT64_SYSCALL.
	* sysdeps/unix/sysv/linux/alpha/fxstatat.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/lxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/xstat.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/xstatconv.c: Don't define
	__libc_missing_axp_stat64 when it's not needed.
	* sysdeps/unix/sysv/linux/alpha/xstatconv.h: Likewise.
