Well, you are doing stuff in your own little corner, all right. The fact is
that the below has no chance of being productive, since the glibc will not
change until the sarge release, and after that there will be a new glibc
anyway, with ppc64 support, and all the other goodies that have been missing.

Oh, so you created an alioth project, what about inviting people interested in
the topic to join ?

That won't do, and i doubt this is the right way of doing it. Please speak
with the glibc people, and try to see if there is a non-sarge devel glibc out
there ?

So, why not have an open discussion with the proper people about this ? Also,
you are aware that there is a debian-glibc mailing list, which would be
apropriate for this kind of discussion, preferably CCed here. Also, i believe
there is a glibc CVS or SVN with a debian devel version.

It will not be accepted, i can guarantee you that. Try to work with the
debian/glibc people, much easier and constructive for everyone involved that

So, you are going to fork debian over a hacked glibc ?

So speak with them.
