info gcc --index "optimize options" says the default is '-O0'.

"-O3" was a typo, I meant "-O2". And I'm not against an absolute
increase in size, just a significant one (>10% is about where I'd start
to care)

No, athlon-xp is valid:
"The second-generation Duron, the "Morgan" core, was sold in speed
grades between 900 and 1300 MHz, and was based on the 180 nm "Palomino"
Athlon XP core." [wikipedia.org]

And -mfp-math=sse actually does nothing because there's not supposed to
be a hyphen between "fp" and "math".
