That doesn't help much IMO.  The copy (the fake symlink) is not complete, so 
it's still a failure.

I think it would be useful however. If you do  :

mkdir gnats; cd gnats; ln -s ../* .; cd ..; zip -r gnats.zip gnats

then the gnats.zip compressed archive would be the same if pseudo-symlinks are 
created in the way which I propose as if real symlinks were created. Therefore, 
if you keep pseud-symlinks as they are, the outcome is farther away from what 
you get with real symlink than which the fix which I propose.

I'm not able to confirm.  When ran the commands on Linux, I ended up with a ZIP 
archive with lots of nested gnats directories.  If we were to break recursions 
on MSYS2 as you propose, the archive would have just 1 level of nesting.
