Code contributed by Yoshioka Tsuneo
(QWF00133@niftyserve.or.jp/tsuneo-y@is.aist-nara.ac.jp),
to support better zlib compatibility.
This code is not _officially_ part of libbzip2 (yet);
I haven't tested it, documented it, or considered the
threading-safeness of it.
If this code breaks, please contact both Yoshioka and me.
