* cygerrno.h (seterrno_from_nt_status): Declare.

Browse Source 
(__seterrno_from_nt_status): Call seterrno_from_nt_status.
	* errno.cc (seterrno_from_win_error): Set errno without calling
	set_errno to avoid packing strace output with errno messages.
	(seterrno_from_nt_status): New function to print NT status as well as
	resulting Windows error.
