--- Comment #1 from Wayne Davison <wayne at opencoder.net> ---
Yeah, the whole -zz idiom was not the best way to have implemented the
internal/external compression idiom.  I'll look into what options we have to
make it better.

The best way to improve how rsync can interacts with an older rsync that is
using the internal zlib is to somehow fix the external-zlib compression support
to make them both compatible. That was the original intent, and while it often
works OK it likes to fail in strange ways, so I ended up making it complain and
die to avoid the potential for corrupted data or aborted transfers. If anyone
has time to look into why the two get out of sync, that would be very helpful.
