how do I determine which of the stage3 installation files:
stage3-athlon-xp-2005.0.tar.bz2
stage3-i686-2005.0.tar.bz2
stage3-pentium3-2005.0.tar.bz2

Ack! What? It does *not* go up to -O9 and never has.
Optimization level 9 (-O9)? Thats a laugh. Read the GCC man page, the
optimization levels are just groupings of other optimization flags (-O1, -O2,
-O3, -O0, -Os), with optimization level 3 (-O3) containing the most
