Sample for case 1

Two cases of file renamings involving symlinks fail:

Case 1: A regular file, named "regular", and a symlink named "symlink" pointing
at "regular". Rename "regular" to "symlink" (which should overwrite the
existing symlink). This should leave one single file, a regular file, named
"symlink". In practice, no rename happens (but no error is reported either).

Case 2: A symlink pointing at a missing file. Renaming the symlink with
MoveFileEx fails.
