The issue is that zlib has changed the way gzFile is defined meaning 
that we now need to explicitly cast from void * to gzFile in c++ code. I 
have attatched a patch that adds the nessacery casts.

The patch contains a NMU changelog entry. If I don't get any response 
from the maintainer I will ask my AM to upload this as a NMU.
