I don't know this part of the C library too well, so I don't have an opinion
on how to do that.

Jeff is in contact with binutils people. But we have found another package
that fails to build. Openldap thinks sys_errlist is defined and tries to
use it in favor of strerror (I don't know why it thinks that is better, but
there you are). I won't notice such things myself anymore, because I
removed that stuff from my local copy, so I don't know if there are even
more.
In other words, this is kind of important for us, and it would be good to
have a fix in the 2.2 branch.
Thanks,
Marcus
