The .o object files should stay with .o as the final extension.

Thanks. I'll try to do this.

My other workarounds instead are:

- recompile gcc so it doesn't do this in the first place

- fix or create wrappers for all tools that potentially use the filenames
with the dynamic ".exe" extension.

The problem is that filename and filename.exe are the same file and some
tools automatically append an ".exe" and some don't and some do it at the
wrong time. I'd prefer if I never saw the .exe in the first place.
