+ * 
+ *	Added {system,sub and code}_emask 
+ *
+ *  12-May-88 Mary Thompson (mrt) at Carnegie Mellon
+ *	Changed mach_error_t from unsigned int to kern_return_t
+ *	which is a 32 bit integer regardless of machine type.
+ *      insigned int was incompatible with old usages of mach_error.
+ *
+ *  10-May-88 Douglas Orr (dorr) at Carnegie-Mellon University
+ *	Missing endif replaced
+ *
+ *   5-May-88 Mary Thompson (mrt) at Carnegie Mellon
+ *	Changed typedef of mach_error_t from long to unsigned int
+ *	to keep our Camelot users happy. Also moved the nonkernel
+ *	function declarations from here to mach_error.h.
+ *
+ *  10-Feb-88 Douglas Orr (dorr) at Carnegie-Mellon University
