OK problem fixed. It was introduced in DIR.LIT 3.0(140) when adding the /NA (native) option. It's fixed in 3.0(142). You should be able to just execute ASHUPD.LIT (for both Windows and Linux) to get it (assuming you have outbound access to the Internet).
If, for some reason you can't get that to work, you can also grab just the LIT file here:
DIR.LIT 3.0(142)
