Fisrt thing is I still don't catch why you can overclock... I understand that someone is afraid to (I am too, so I don't until my system is well behind new market products so the increase of perfomance is desired using many programs and I break somthing is cheap to replace or can upgrade to something better ;-) Anyway, there are programs that do the overclock directly into mainboard/graphic bios so you can do them from DOS/Windows and make them permanent (dangerous, as well).
I can't overclock because may mainboard cannot!
I think option -O4 maybe specific to a certain compiler (egcs, for example). In the past I used djgpp (amazing gcc port to DOS) and also used a now dead fork of it for pentium specific and had up to -O6 !!! I just googled a bit and have seen it exists in egcs :-)) and there are also some proposal of -O4 optimizaion standard.
Are differencs between agcs and gcc?
I'll try them and I'll report the results...Humm, I didn't know all the info it provided! ;-)) If you want to go on with gcc optimizations, you can try adding: -fexpensive-optimizations to Makefile and playing with: -funroll-loops -funroll-all-loops -malign* options (these will speed up things but may and probably should overfill cpu cache so effect can be positive or negative depending on each program and each cpu power/cache size ratio).
