It's a valid OS path.  The unfortunate side effect of its virtuality is
that it's not listed in a readdir call, so file completion doesn't work.
However, there's a funny workaround.  Just start an elevated bash:

  $ cd /cygdrive/c/Windows
  $ export CYGWIN=winsymlinks
  $ ln -s temp-file-name sysnative
  $ cmd /c ren temp-file-file.lnk sysnative.lnk

Now try

  $ cd
  $ cd /cygdrive/c/Windows/sysn<TAB>
