Bug#2343: libgz obsolete and confusing name for libz

[Helmut Geyer <Helmut.Geyer@IWR.Uni-Heidelberg.De>]

Package: libgr
Version: 2.0.5-3

The compression library libz.{a,so*} is called libgz.{a,so*} . While
this was needed on an a.out system containing an ancient version of
the transparent decompressing libc plug-in (which was, alas, called
libz), this is not needed on an ELF system and when using a recent
zlibc package (which does no longer use a replacement library but the
LD_PRELOAD mechanism). Furthermore, this library is a non-standard one
while lib[g]z seems to become a highly standard one once PNG replaces
GIF as standard format for WWW high-quality pictures (PNG is a W3C
Working Draft right now).

As all packages using the compression library zlib (e.g. all packages
containing PNG support) want to use -lz, I strongly recommend changing
the library name to libz.* . For backward compatibility links libgz.a
and libgz.so should be supplied for some time.

We should _not_ name a standard library differently than all other
systems around the world.
