I am still looking for a way to transform POV-Ray objects (such as unions,
basic shapes, differences or intersections) to POV-Ray meshes.
Who can help?

It's not possible, at least not currently.

Shh, don't tell Moray 3.5 that...

It can convert POV-Ray SDL to meshes?

It can convert POV primitive-based CSG objects into meshes. Yes, you
have to build them in Moray, but when you render it before converting to
mesh, it's still a POV object. That's what was quoted and to which I
responded, nothing about POV SDL. *wink*

There's a way to do it in povray's SDL, which is kinda clunky.
It essentially would turn this:

into this:

I'd have to find out where and if I've published my own code for this. But
it involved the trace function and the makemesh macros.

A "Make_Mesh" macro? Hmmm, that sounds quite interesting! I am going to
research on that macro! Thanks, Greg!

It should be possible to implement the marching cubes algorithm [1]
in SDL using an object pattern. This would probably give better
results (in particular, the arms wouldn't be attached to the sides
of the body).

Actually Moray can export primitives and evaluated CSGs to mesh without
3DWin.
In Moray, the" transform to mesh" feature is based on the display triangles
and quads so you can set the wireframe division in the "advanced" tab of the
configuration (Alt+O) settings.
Moray exports the result as mesh or mesh2 if you want.
