I've tried adding ld.exe and as.exe, and altering the path (at runtime
which Eli says is bad).

I am now getting this error message; it's different so that's obviously
part of the problem.

   Warning (comp): Debugger entered--Lisp error: (native-ice 
"c:/msys64/home/Administrator/emacs-upload/emacs-28..." "failed to compile" 
"c:/Users/Administrator/AppData/Roaming/.emacs.d/el..." "error invoking gcc 
driver") Disable showing Disable logging


I'm try following up on jit@gcc as you suggest. They may well know what
I need for a minimal functional install. Once I have that, I can work
out how to achieve it in the package. At this rate, though, I fear that
I am moving back to shipping half of msys.
