The eglibc has had its last release in 2.19 and btw. the release
branches in eglibc will get backports and fixes
as long as corresponding glibc branches are open. As of now eglibc
trunk has ceased to exist. I am waiting on 2.20 glibc release (which
should be happening anytime now)
there is a list of changed in eglibc that are not in glibc the reason
being no one carried them forward and partly I am also  to blame due
to time constraints but I will make up for it :)

- ppc/e500 has few changes around SPE which our FSL/ppc bsp might care
- Option group support - As Paul mentioned we use it and I plan to
forward port it and possibly submit it for 2.21
- cross-localedef - We care about it. We have to see whats missing in
2.20 and forward port the missing parts.
- cross testing - There are minor adoptions needed but we dont have
ptests for eglibc yet so this should be minor

Rest of items which are left out doesn't bother us.

We are in August. I am hoping that we can include 2.20 in 1.7 release
but there might be a risk associated due to above
and that we will change recipes to be called glibc instead of eglibc
some metadata changes have to be made as well. I hope to work on it
starting second week of august.

Hope that helps
