/*
* This file is derived from various .h and .c files from the zlib-0.95
* distribution by Jean-loup Gailly and Mark Adler, with some additions
* by Paul Mackerras to aid in implementing Deflate compression and
* decompression for PPP packets. See zlib.h for conditions of
* distribution and use.
*
* Changes that have been made include:
* - changed functions not used outside this file to "local"
* - added minCompression parameter to deflateInit2
* - added Z_PACKET_FLUSH (see zlib.h for details)
* - added inflateIncomp
