One way to handle this would be to check if the thing found in the path looks like a symlink (say, by having a size less than a hundred bytes and the 'S' attribute set) and if so, launch it as "sh.exe -c python", using sh.exe in the same dir as the shortcut. This will invoke python through the shell, which will follow symlinks. Non-cygwin programs will have no idea what a symlink is.
