buffer overflow in recv_file_entry

[Jakob Unterwurzacher]

I have a backup job failing because of a long path with error message
(full output below, [1]):

> overflow: xflags=0x2078 l1=255 l2=775 lastname=looooong path....
> ERROR: buffer overflow in recv_file_entry [receiver]

It looks like the remote system (a Hetzner Storagebox) for some reason
has a maximum path length of 1024 (like in [2]), and I cannot change
rsync on the remote end.

My question is what I can do on the local end to not abort the rsync
run on long paths. I would like rsync to skip the file and move on.

Maybe compile the local rsync with MAXPATHLEN=1024?

Thanks,
Jakob
