 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.
