From e6634087a1c47f490bb8238dcc259e057aed6e10 Mon Sep 17 00:00:00 2001 From: Martin Simmons Date: Wed, 9 Nov 2011 19:16:39 +0100 Subject: [PATCH] Move Zdeflate and Zinflate to seperate file. Move Zdeflate and Zinflate to sr/lib/binflate.c from src/lib/bsys.c, to allow various executables to link with bsys.o without pulling in functions that need libz. This is needed because some of Bacula's executables don't link with libz, but they do use code from bsys.c.
