 *	Name:		mkldir_path.c
 *
 *	Description:	Make a labeled directory path.  Including any missing
 *		path elements.  Equivalent to the "mkdir -Z label -p" command.
 *		This routine should not use dirname() since it might be called
 *		with the return value of dirname() call.
 *
 *	Note:	If name points to read-only memory, then this routine will fail.
