Yeah, there is no low-level equivalent of a symlink on Windows. They use
files with a .lnk extension whose format is not really documented and
which are interpreted by the higher level Windows Explorer shell. The
.lnk files also contain a lot more information than simply a pathname.

I'm not sure how cygwin handles symlinks, maybe they try to create or
parse those .lnk files, in which case Coda might be able to represent
symlinks as files with an .lnk extension.

Deceptive error, which probably should be 'is not a file', but I guess
that either that error is not available as an errno value, or not a part
of POSIX. We'd never see an open attempt coming from the kernel for a
symlink on UNIX systems since they are automatically redirect the open
to the link target.
