* hurd/hurdselect.c (_hurd_select): Fix

	MACH_MSG_TYPE_INTEGER_T -> integer_t in sizeof.
	Use a union rather than casts to compare mach_msg_type_t as int.

2002-03-25  Roland McGrath  <roland@frob.com>

	* hurd/hurdchdir.c (_hurd_change_directory_port_from_name): Don't
	check off the end of NAME when it's shorter than 2 chars.
	Reported by Ognyan Kulev <ogi@fmi.uni-sofia.bg>.

2002-03-17  Roland McGrath  <roland@frob.com>
