i386. I just checked into CVS a couple of minor changes that reduce that
figure to 97 KiB, BTW :^)

That depends on your toolchain; I can't say if there's anything else that
yours generates that's superfluous. My old gcc 2.95.3 PPC toolchain doesn't
leave me any obvious candidates. I should note that it's also generating
code that's 36% larger than for x86.

The debugging sections should already be removed with one of the strip
options mentioned there. You might be able to remove the .gnu.version*
sections if you fiddle with some other fields, but there's probably not
much else.

This patch will save another few KB:

If you're this concerned about size, you may want want to investigate if
you can use CodePack compression or some other kind of run-time code
decompressor.
