Actually, changing CFLAGS to -O2 has a huge effect. IF you do that (knowing it's unsupported), you will also have to add -fno-strict-aliasing. As for CPUTYPE, I had luck with p3 in the past, but I have since reverted to the default. All Pentium 4 types are known to cause problems as are some Athlon types.
