I run Windows 10 and that works for me. Of course below, jcontrol should
be an actual file, while ControlPanel will be a symlink to it. (That
particular name might behave oddly under Windows, because the Control
Panel is a built in thing!)
Not sure what else to say about the different forms. The lnk form, as
I recall, builds a Cygwin-specific thing that Cygwin understands but
Windows tools will not - they'll just think its a small ordinary file
(its has within it, a few "magic" bytes then the name of the target
file). You _want_ a short-cut, right? ControlPanel -> jcontrol _is_
So I admit I am not fully understanding your post.
Also, on this list, the custom is to bottom-post (or intersperse) replies,
not to top-post.
