I tried that on C:\cygwin; it gave an error message without copying
anything.  I suspect that was because this directory tree included
links to the top-level directories of all of the Windows drives,
including the one holding the Windows 7 operating system.

I found a way to see the robocopy instructions; it looks like I'll
need to read them thoroughly in order to tell it to copy the links
but not what they point to.
