Aw! I'd feared such would be the case

I'll do that, time allowing. It's not particularly important that I find out out exactly what's missing, since AFAIU (from personal mail), Japheth has got got other business now than caring after HX. I was a bit surprised that Bochs compiled by me with a vastly restricted set of capabilities than the official build (removing AMD64, VMX & more) did not work using HX, while their version does. Either due to using different MSC++ compilers, or some device I included and they did not. Again not a real grief, I was just being curious.

Yes, by-ordinal-imports are an additional liability
