Right, I need to isolate the effects of each variable. Results for gcc
3.4.4 and 4.0.2, built with CONFIG_CC_OPTIMIZE_FOR_SIZE enabled, appear

Yes, thats more like the rest of the results I seen... BTW, what is the .config?
Here are my results. Kernel is 2.6.15-rc7, gcc is 4.0.2 (Gentoo 4.0.2-r2,
HTB-4.0.2-1.00, pie-8.7.8)
'ay' denotes allyesconfig, def is defconfig.
I believe that neither of these have OPTIMIZE_FOR_SIZE turned on, but I didn't
play with that.
allyesconfig made a huge kernel, so I manually 'fixed' the formatting.

defconfig:
17674 byte difference (0.4%) in text.
allyesconfig:
128142 byte difference (0.6%) in text.
Unless my math is off, that is.
