If you invoke runemacs.exe it picks up its environment from the mingw64
shell. That means anything installed on the local machine to the
/mingw64, any dlls, anything will be available to Emacs, even if they
are not present in the bundle.

If you invoke runemacs.exe by clicking on it in explorer, then it only
looks for DLLs in the same directory (and what ever windows normally
does I guess).

So, I have the right dependencies installed on my build machine, but
haven't packaged them up correctly.

Hmmm. I don't know why I see that. No, I am not cross building.

Not in my package at the moment. I have tried adding it next to the
runemacs.exe, and expected that to work, but it didn't.

When I become world dictator, I shall people from naming their software
