can someone explain the new layout of glibc tarballs?

My guess is that the 2.3...20051024 ones are snapshots of the 2.3
branch (on the way to some possible future 2.3.6),
and the ones without 2.3 on them are snapshots of
the 2.4 branch (on the way to some future 2.4.0).

I haven't tried it, but all the glibc addons are probably similar;
you unpack the main glibc tarball, then cd into it and
unpack the addon.  And that's your source tree.
See how my getandpatch.sh treated glibc-linuxthreads-$version.tar.gz,
and treat glibc-ports-$version similarly.
That's my guess, anyway.
