Dear JCB,
while you're at it, beside making it work with the latest 3.1, you can look at the ECL-only tests and mkcl workarounds in the tests (grep for ecl and mkcl tests/ and subdirectories). It would be great if you could make them work on MKCL, too. test-bundle and test-program notably are likely buggy on MKCL, since they are not tested.
