Actually, additional info is not important, so you can stop looking
for it.

In Emacs 24.3 and earlier, copy-file called a Windows API that doesn't
set errno, and Emacs itself didn't check Windows-specific errors
triggered by that API.  So you can get any error at all reported
there.

The development trunk does check errors and sets errno accordingly, so
you get either "Permission denied" or "Access denied", and nothing
else.

Sorry I didn't check the code earlier.
