problems building 2.9.17+ from CVS; surface.m implicated

[Joseph P. Skudlarek]

I tried a second build of Octave from CVS sources (having just done an
update), and I'm seeing this consistent failure.

    ../../run-octave -f -q -H -p . --eval "interpimages ('interpn', 'eps'); 
sleep (1);"
    error: surface::defaults: not implemented
    error: called from `surface' in file

    error: evaluating assignment expression near line 37, column 7

`/usr/local/src/octave-cvs/octave/scripts/plot/mesh.m'
    error: evaluating if command near line 21, column 3

FYI, I also saw these messages on the first build attempt; the plot.texi
warnings did not show up on the second build attempt after update (with
no noticed updates).
