I don't think cygcheck can resolve a symlink.
(I'm not near a Windows machine to test right now)
For the archives, yes, it can.
I don't have emacs on my machine (vi is the one true editor) but the
only difference between the two invocation methods is that if you pass a
symlink, cygcheck emits an extra line at the start indicating that it
chased a link. Something like this:
-> C:\cygwin\bin\emacs-nox.exe
I tested this with /bin/infotocap vs. /bin/tic.exe.
(Why that pair? It just grabbed my attention first after ls /bin.)
