Bug#337056: libc6-i686 always flagged as orphaned by deborphan

[Eric Valette <eric2.valette@francetelecom.com>]

Package: libc6-i686
Version: 2.3.5-7
Severity: minor

-ptxp-ceva6380:/home/ceva6380# deborphan
libc6-i686
r-ptxp-ceva6380:/home/ceva6380# 

While this is my libc on my system. Can we find a way to mark 
it as non orphaned even if no packages depends explicitely on it?

NB : the problem is that normally I use deborphan output directly as 
input of dpkg --purge...
