#_ Holy smokes!!! You're crazier than I! I never compile my kernel with

This is how crazy I am: in /etc/profile I put in a variable:
BOYOYOY="-O6 -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 -fno-strength-reduce"
#(I don't remember where and when I got all this cr*p)
export BOYOYOY
When I edit a Makefile, I just put in:
CFLAGS = $(BOYOYOY)
(I do this for /usr/src/linux/Makefile)
In /usr/src/linux/arch/i386/Makefile; I change "-march=i686" to
"-march=pentiumpro"
Sheeez talk about anal ;->
