Athlon, 512 Mb ram, Win ME, beta 8(both compiles)
IsoCacti.pov in advanced dir gives dozens of max_gradient found
was 0.000 warnings for line 73.
Is this a bug or a case of "bad" functions?

I think it's a consequence of this change (from changes.txt)
Change 1239 on 2001/11/02 by thorsten@host27
Some more isosurface changes to re-enable 'evaluate', which is
now only responsible for the 'dynamic max_gradient' method.
The found maximum gradient will always be printed based on
certain rules. It is no longer necessary to use 'evaluate' only
to see the found maximum gradient!
There are 754 isosurfaces in the scene (the ground, 3 cacti and 750
small stones) and an evaluate warning is displayed for each one of them.
(It's a good job the "too many evaluates" bug got fixed).
The details of the evaluate warnings are not correct. Many of them
suggest that the max_gradient should be changed to 0.000, but that's not
a legal value.

Two additional problems :
- giving a max_gradient doesn't remove the warnings
- putting -GW on the command line doesn't remove the warnings either (-GA
does remove them and the statistics)

Yes, the estimated max_gradient is now always displayed in a warning if it
differs too much from the given one. The warning displayed with dynamic
max_gradient (evaluate) is the same although this is misleading and will
probably be changed.

I never used text streams so I can't really tell you how those work, but I
can tell you that it is easily possible to turn off warnings and only
warnings. The information is in the appropriate place in the documentation.

Yes, that's exactly what I'm saying (see 5.2.5.2 Console Text Output)
-GW turns off the warnings, but not the new isosurface warnings.
Right now, the only workaround to turn off the iso warnings is to use -GA,
which removes almost all the text output.

It is in section 5.2.5, maybe you should read the whole section. All you do
right now is hide the warnings, but you can really turn them off!

But you agree that there's a bug of some sort: I have too a scene with
several hundred isos and, once POV-Ray has finshed to trace, I have to wait
a minute for all those warnings saying that the maximum gradient found is
0.000.

It does this only if the gradient found was really zero, which can i.e. be
the case if there was no intersection. I will adjust the warning message to
ignore such cases, yet.
That Gilles can't turn off the warning with -GW is also not correct,
however, there is a much better workaround than - GA in section 5.2.5.4 of
the documentation, which explains the warning level option. Hopefully
Gilles has found it by now...

I personally got rid of them with +wl0.
