True, but we're way to close to a release to fix *that*. And I'm not
sure that we could easily fix binary-i386 at all..

Looking in that archive, this was first discussed in April 2003:
Debian to drop Support for i386? Jochen Friedrich noted that
due to GCC 3.2 the new libstdc++5 library requires an 80486
processor or higher, the old 80386 on which Linux was started, is
no longer supported. Therefore Matthias Klose wondered whether
Debian should further support the i386 target.
Dropping Support for i386? Nathanael Nerode investigated the
i386 problem and discovered that to maintain binary compatibility
with C++ packages from other distributions, Debian needs to use the
i486 version of atomicity.h supplied by GCC. Dagfinn Ilmari
Mannsåker wrote a small script that compares the speed of
OpenSSL code for i386 versus i486 on a P-III Mobile.
Another URL that was inspired by and mentioned on the debian-release
mailing list: <http://people.debian.org/~joey/pr/3.1/i386.html>
Hope that helps.
