Update.

2000-01-18  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/i386/lxstat.c: New file, handles 32bit UIDs.
	* sysdeps/unix/sysv/linux/i386/fxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/xstat.c (__xstat): Move
	_STAT_VER_KERNEL handling up; don't save errno.
	* sysdeps/unix/sysv/linux/arm/fxstat.c: New file.
	* sysdeps/unix/sysv/linux/arm/lxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/arm/xstat.c: Likewise.
	* sysdeps/unix/sysv/linux/m68k/fxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/m68k/lxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/m68k/xstat.c: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc32/fxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc32/lxstat.c: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc32/xstat.c: Likewise.
