[AuckLUG] CFLAGS options

[Chilling_Silence]

Greetings Tim,

Ive done a complete Gentoo system recently with -O3 without a problem 
(Kde, e17, OpenOffice, Firefox, thunderbird etc), using many more CFLAGS 
than mentioned previously for my x64 system.

http://gentoo-wiki.com/CFLAGS may be of use :-)

Cheers


Chill.
