Well, that’s . . . awkward :-)

Yah, that’s what I thought.  Thanks for confirming.

Hah.  Well, I don’t want to rip it out of the system entirely, but I do want to isolate it to only the places where it’s useful.  If the number of those places is currently smaller by a handful, that is not my concern :-)

I suspect the number of people using Xylogics SMD controllers on NetBSD/sun3 or NetBSD/sparc is also approximately NIL.  But I don’t want to throw anyone under the bus.
