CFLAGs for kernel compilation

I have upgraded my system to ELF, installed gcc-2.7.2p, and
libc-5.3.9. Both gcc and libc are the Pentium specific versions.
I am wondering if there is a "better" set of CFLAGs for use
for compiling the kernel than the standard 1.2.13 CFLAGs.
I have tried changing the "-O2" flag. "-O6" through "-04" produced
non-booting kernels. "-O3" produced a booting kernel.
Thanks in advance for all responses.
