That makes sense but it would be a LOT of work for many people (well,
a lot of small work for many people).

How about this kind of modification for the setup program: extract tar
archives into temp dir, after that search that temp dir for symlinks,
if they don't match the current winsymlinks option, recreate them
appropriately?

I just remembered what I did when I first discovered the winsymlinks
option (already having a 32-bit Cygwin set up for a couple of years).
I tarred my entire cygwin directory, copied it over to my Linux
server, untarred it there - which created all the symlinks, including
Cygwin's symlinks, as proper symlinks, then tarred it back, copied
back to the Windows box, untarred - voila, all symlinks are created as
native. I wonder how are Cygwin vs native symlinks stored inside tar
archive - tar knows they are symlinks but also knows which ones are
native vs Cygwin's. That's a whole lot of bother, though, and now that
I know that some further package update down the line might replace
native links with Cygwin links again (didn't expect that), I wouldn't
be willing to go to that trouble.

It should work out of the box automatically, in my opinion. Cygwin
symlinks are a kluge (e.g. I can't edit them in Far manager, the way I
can adjust a native symlink), and if using Cygwin exclusively on NTFS
filesystems, supporting symlinks, I can't see any reason to have any
on my system. The proposed solution is sensible, but it spreads
responsibility among all the package maintainers, and it will take a
long time to reach.
