Re: [Yafray-devel] ppc again

min_raydis=0.0000000000001;
seems to work, so just by removing one zero.

I'm using gcc 2.95.4 on both systems(x86 and ppc), might be intresting 
to see what
happens with gcc 3.x?

With the #ifdef __PPC__ and the same for windows, how about other platforms,
they would all have to be tested seperately? Or is it safe to assume 
that most systems
handle this properly? Or maybe somesort of an testing system at 
compilation time.

Just curious...
