Update.

1998-12-01 09:47 -0500  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* sysdeps/unix/sysv/linux/sys/timex.h: Copy out
	user-space-relevant definitions from linux/timex.h of kernel
	2.1.130 and remove include of kernel header.

	* sysdeps/unix/sysv/linux/adjtime.c: Remove portability crud.
