bloated.. hmmm... the debian machine at my feet is currently at 180M

are we back to it's faster because I use these flags?

if you really feel that's the way forward, off you pop...
gcc is known to not be great on optimizations... good thing you're not using
an alpha I guess.. you'd be wondering why 95% of your programs didn't
compile or segfaulted when you tried to run them.
I think if you add together the time saved by not compiling everything from
source when a new version comes out, and take away the time you lose by not
optimizing, it won't make a huge difference. I'm not suggesting the flags
won't make povray or something run a lot faster, I'm talking on average.
LFS and distro's that build from scratch are just another way of proving
"I'm more leet than you are". And in a lot of cases (I don't know about you)
the people doing it are dumping the knowledge RedHat, Debian and SuSe have
built up about how to build a package, and know next to nothing about how
-f... affects the compiler..
