Okay, that makes a lot of sense. That's something I didn't know.
So I went through all those different USE flags, and added ones I knew I could
add without anything blowing up. This is what I get:
# These settings were set by the catalyst build script that automatically
built this stage
# Please consult /etc/make.conf.example for a more detailed example
#CFLAGS="-O2 -march=i686 -pipe"
CFLAGS="-march=i686 -O2 -pipe"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"

If anyone has any suggestions to further fine-tune this for a Pentium-M 1.0
GHz Ultra-Low Voltage chip, please tell me.

I looked and they were already there. However, MMX, SSE and SSE2 were not
enabled, so I enabled those.

I'll try that just a little later, when I can leave my laptop without needing
to use it for anything, so that it can happily chew away at everything
without my needing to lag through other things.

It did! Thanks a bunch. I'm going to have fun tweaking my system for maximum
performance (one of my favorite passtimes while coding, I have to admit) with
these new options open to me!

I'll put them on my "to-read" list. Right now I've got to go hunting through
MSDN for some junk on Visual C/C++/C#, for work. I don't normally go to MSDN
of my own accord, other than to check up on them and make sure they're still
there making millions of people angry.
