Actually, in the meantime I have been able to test this code
in another linux environment and I couldn't reproduce
the problem. So, it may have something to do with my C compiler
or maybe with the gs version ?

I have also run into other problems and I will write about
them later. I have both problems of parts sometimes not appearing
(for instance some faces of a standard icosahedron not colored,
when the others are), and problems with text. I haven't been
able to control the position of TeX text, even with the
GL2PS_TEXT options. Do you have a working example?

One small problem with LaTeX output: gl2ps
outputs ``\makebox(0,0)'', but it should output
        ``\makebox(0,0){''

Thanks again for your great package!
