There has been an early 3.5 official binary version compiled without 
optimization but the current official version is compiled with -O3.  And 
as you also observed some time ago the speed advantage with using more 
fancy (processor specific and possibly faulty) optimizations is 
marginal.  There is absolutely no need to compile POV-Ray from source 
just for the speed advantage (to actually save time this way, even if 
you have experience compiling programs yourself, you will have to render 
quite a lot of very slow scenes).
