Re: [expert] compile for i686

[Jean-Michel Dault]

Here are the flags to optimize for i686:

optflags: i686 -O3 -fomit-frame-pointer -fno-exceptions -fno-rtti -pipe -s
-mpentiumpro -mcpu=pentiumpro -march=pentiumpro -ffast-math 
-fexpensive-optimizations -malign-loops=2 -malign-jumps=2
-malign-functions=2 -mpreferred-stack-boundary=2
