[Coco] Issues with NitrOS9 build

[Bill Pierce]

You say this fails in VCC 1.4.2?
 I will do a fresh pull/make in a bit and try it. 
My current setup uses Vcc 1.4.3b and DW and my pull from 2-3 days ago works fine there but you said the 40trk & 80 trk so I'll try them on 1.4.2

Which is *exactly* what I'm using, and always have. I only very rarely use 
3.5" disks, and in fact don't have such a drive connected now.
