Optimized gcc 3.2.2 compiler...

I'm tinkering around with building an optimized gcc 3.2.2 compiler and have come
up with what I suspect is good for my old k6-2 laptop. Would any of the gcc
builders here have a look at what I'm doing and possibly make recommendations
where I've over looked anything?

gcc-3.2.2/configure --prefix=/usr --enable-threads
--enable-languages=c,c++,java,objc --disable-nls --with-system-zlib

make BOOT_CFLAGS="-O3 -pipe -fomit-framepointer -funroll-loops -march=k6-2
-cpu-k6-2 -mmmx -m3dnow -mfpmath=387" bootstrap


The resultant gcc compiles good code and seems quite fast. Any pointers or
recommendations would be very welcomed as I'm a programmer/compiler weeney...

Thank you, in advance.
