Update.

2002-03-20  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/x86_64/sys/user.h (struct
	user_fpregs_struct): Fix for changed kernel struct.
	(struct user_regs_struct): Likewise.
	(struct user): Likewise.
	Add 32-bit x86 compatibility.

	* sysdeps/unix/sysv/linux/x86_64/sys/reg.h: Add more registers.
