	DOS error codes (and eventually NT Status codes) are accessable from
	SmbException as defined in the Leach/Naik/SNIA document. See my
	recent example and jcifs/smb/SmbException.java

	The errno approach is inferior to exception handling and we should therefore use
	it. The only difference being there is only one Exception class for all of the
	possible error conditions because there are so many possibilties (hundreds).

	This is 0.5. We're allowed to do this. I think it's a necessary change and will be
	appreciated in the long run.
