59 * input in strm.
60 * - Fixed stored blocks bug in inflateBack()
63 * - Added comments in inffast.c on effectiveness of POSTINC
67 * - Changed type of window in inflateBackInit() to unsigned char *
75 * for the in() and out() functions
80 * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.
