The link has been created correctly already the first time you called ln.
The problem is that ls doesn't evaluate the information correctly because
the underlying path handling finds the "tcsh.exe" file before it finds
the "tcsh.lnk" file.

While this is a problem which could be "fixed" in some way in Cygwin, I'm
nevertheless wondering how you want the ambiguity to be solved.  If you
type "etex" on the command line, do you want etex -> pdfetex.exe to be
started or etex.exe?  Regardless how that's solved in Cygwin, it will 
work contrary to the expectations in 50% of the cases.
