When reading a new block of data, and the first byte of the new block is 0xff (_signed_ char -1), then this must be converted to _integer_ 0xff (+255), not -1 - which would indicate an error condition (EOF==-1). All valid _data_ character must be returned as non-negative, see streambuf::underflow spec, or compare with http://www.opensource.apple.com/source/zlib/zlib-12/zlib/contrib/iostream/zfstream.cpp or http://www.raspberryginger.com/jbailey/minix/html/zfstream_8cpp-source.html
