Please show us the actual command line you typed, rather than a
description of it; even better, starting from an empty directory, show
us a sequence of mkdir and touch commands that will get us into the same
state to reproduce the message you are complaining about.  However, I
suspect that this is not a bug in ln, but a misunderstanding on your
part.  Cygwin, like Linux, prohibits the creation of hard links to a
directory, and POSIX permits this restriction.  Just because Solaris
chose to allow hard links to a directory does not make it a good idea.
