Re: VectorEnginePlugin changes circa march 2026

(& ignore my request for the OS; I was being blind; Sorry)

But can you run e.g. dumpbin /exports on VectorEnginePlugin.dll?

Here's what i get on an ARMv8 Windows build. Looks like everything is in
place:

Z:\oscogvm\building\win64ARMv8\squeak.cog.spur>dumpbin /exports
