Fix for Hurd/BSD times() implementation

[Mark Kettenis]

More fall-out from the CLK_TCK changes.

Mark


2001-02-10  Mark Kettenis  <kettenis@gnu.org>

	* sysdeps/unix/bsd/times.c: Reorder includes and add <time.h>.
	(timeval_to_clock_t): Add clk_tck argument and use that instead of
	CLK_TCK.
	(__times): Use __getclktck to get the number of clock ticks per
	second and use its return value instead	of CLK_TCK.
