I'm pretty sure Cygwin itself has a 2GB (32-bit) limitation for files.
Large file (64-bit) support for Cygwin has come up in various ways
repeatedly on the Cygwin mailing list but it generally ends up at the point
where if someone is asking for it, the suggestion is that they implement it

So I don't think there's any practical workaround with Cygwin.
