1) Nobody mentioned amd64 - this is about i386.
2) It's not a question of *size* but of *performance*. By targeting the
least capable platform that our users are likely to encounter
(pentium-mmx) instead of one which is virtually eradicated (486), we
can use features that are available on the former but not the latter.
Someone said they'd like to target SSE2, but that would leave many
common embedded systems out in the cold. If we do that, we should
provide two sets of binaries; one set for sse2-capable machines
(which covers all i386 desktop and server machines made in the last
ten years) and one set for pentium-mmx (which covers the soekris and
other popular SFF / embedded systems).
