I actually tried the -ffast-math option, then tried to render 
balcony.pov and got spammed with the following lines repeatedly:

Warning: Illegal grid value in dda_traversal().
The height field may contain dark spots. To eliminate them
moving the camera a tiny bit should help. For more information
read the user manual!

Weird, huh? Since that scene rendered fine before the -ffast-math flag, 
I figured it's better for me not to use it. Maybe it's buggy with gcc 
2.96 but works with gcc 3.1?

I'll give the other flags a go and run some more benchmark renders.
