No, instead, it was wrongly installed by yourself.

Which is the problem: the unison command was compiled against a newer
cygwin1.dll than yours.  You need to update at least the libraries and
packages that unison depends on, which might be quite a bit, so
upgrading everything will be easier.

Possibly you're even trying Unison-for-Cygwin-1.7 with a Cygwin-1.5.DLL,
but I haven't checked that, and I don't even care.

Please backup your Cygwin path, download a fresh setup.exe and run it.

Update everything that is offered for update.  Do not deselect or set to
"Keep" anything that even remotely looks like it might have to do with
the cygwin base system.  If your old install was 1.5, check the web site
for things that changed in 1.7 and that might need your attention.

If you want to stick to 1.5, you're on your own.
There is no support for the 1.5.X legacy version.
