Ah yes, I remember something about that, too. I also thought it had been
fixed, or had the #version in each inc file to make it automatic.
BTW, I rendered it with official POV and found the same results re glass and
shadows.

Yes, commenting out "caustics" makes the picture look like it did before, re
the lightness of the glass and its shadow. I suppose that in the older
version of POV that was in use in 1997, this did not work, or has been
changed.
(later)
Moving the "caustics" line from the texture to an "interior" block in the
object, as the warning suggests, also makes the problem go away! So this
seems to be a bug in the backward-compatibility feature. Is someone keeping
a list?
