For the poor next soul who sees many valgrind warnings of the "Conditional jump or move depends on uninitialised value(s)" kind: According to the author of zlib it is not a bug and it won't be fixed. http://groups.google.com/group/comp.compression/browse_thread/thread/b154b8def8c2a3ef/cdf9b8729ce17ee2 [Mark Adler, Feb 24 2004, 'zlib-1.2.1 valgrind warnings' in the newsgroup comp.compression]
