Ok, I'll try w/ this flags. Do you know if there is
some other options for Sparc and UltraSparc
architecture ?
Because, POV's configure script doesn't do good stuffs
w/ architecture other than i86 (it's the authore first
trial w/ configure).
For the moment, I use following option :

-O3 -finline-functions -ffast-math
-fomit-frame-pointer -funroll-loops
-fexpensive-optimizations -Wno-multichar

Bye

Lolo
