Thanks. I'm using 64-bit Ubuntu 15.10 with zip 3.0  (3.0-11, which is the
one in the repo.)  Unzip seems to be version 6.00 (6.0-17ubuntu1.2).

The zipsplit manpage says:-
BUGS
       Does not yet support large (> 2 GB) or split archives.

Unless I've misunderstood funzip, it only acts on the first item in an
archive.

Maybe I'll have to try writing a script to do what I want.
