Some added trace shows:

My guess is that 'diff' infers that the two strings name the same
directory, because st_dev and st_ino are identical which means same_file
(which uses SAME_INODE) thinks they're the same file. But that's just a
guess, and someone who can debug the MS-Windows code would have to
verify it.
