Optimization: used "zero" instead of O

[Sadako]

First time using Linux.
I entered -03 instead of -O3 in CFLAGS in make.conf.
I only discovered the error now after finishing the stage 1 bootstrapping, which took just over 4 hours on my pIII 600 MHz with 320 mb ram.
I've already corrected the value, but what I'd like to know is would there be much point in starting again with the proper value?
Will this affect everything else I compile from this point?
What is the default optimization used if a correct value is not supplied?

Thanks.

You're fine. It ignores unregistered values, so unless -03 refers to a compile option for GCC, which I don't believe it does, you're absolutely fine.

Go edit your /etc/make.conf and put in -O3, and delete -03, and that will affect all compiles done from now on.

Feel free to recompile things that need speed...like perhaps rsync, Portage, KDE/GNOME/your favorite WM and all its dependencies...I don't know how much difference it'll make, given that I've never compiled without -O2 or -O3 before, but I believe it should help.

Incidentally, don't bother recompiling everything; you'll end up recompiling it anyway when new versions come out, and if your make.conf is fixed, it'll use the settings in there.
