Thanks John, that patch did the trick, "make check" finishes.

There's now one FAIL I didn't see before in ode15i. No idea if it's related,
excerpt from fntests.log follows:

>>>>> processing /home/philip/devel/octdev/dev/scripts/ode/ode15i.m
***** testif HAVE_SUNDIALS
 saved_opts = warning ();
 warning ("off", "all");
 opt = odeset ("Jacobian", "_5yVNhWVJWJn47RKnzxPsyb_");
 fail ("[t, y] = ode15i (@rob, [0, 4e6], [1; 0; 0], [-1e-4; 1e-4; 0], opt)",
       "invalid value assigned to field 'Jacobian'");
 warning (saved_opts);
!!!!! test failed
expected error <invalid value assigned to field 'Jacobian'>
but got <nargin: FCN must be a string or function handle>
