Roland McGrath 3a2832a07f * sysdeps/mach/hurd/times.c: Fix typo in last change.
* sysdeps/mach/hurd/setpriority.c [POLICY_TIMESHARE_BASE_COUNT]:
	Use task_policy in place of task_priority.

	(__mach_msg_trap, __mach_msg_overwrite): New functions.
	* mach/Versions (libc: GLIBC_2.0): Add mach_msg_overwrite and __ name.

	* sysdeps/mach/configure.in: Check for clock.defs to put into
	mach_interface_list.
	* sysdeps/mach/configure: Regenerated.

	* mach/Makefile (mach-machine): New variable, set from $(base-machine).
	($(objpfx)mach-syscalls.mk): Use it in place of $(base-machine).
	($(mach-syscalls:%=$(objpfx)%.S) static pattern rule):
	Use <mach/machine/syscall_sw.h> instead of <sysdep.h>.
	(mach-shortcuts): Add device_read_overwrite_request,
	device_read_overwrite, vm_read_overwrite, thread_switch.
