9  * This header file and associated patches provide a decoder for PKWare's
10  * undocumented deflate64 compression method (method 9).  Use with infback9.c,
11  * inftree9.h, inftree9.c, and inffix9.h.  These patches are not supported.
12  * This should be compiled with zlib, since it uses zutil.h and zutil.o.
13  * This code has not yet been tested on 16-bit architectures.  See the
14  * comments in zlib.h for inflateBack() usage.  These functions are used
15  * identically, except that there is no windowBits parameter, and a 64K
16  * window must be provided.  Also if int's are 16 bits, then a zero for
17  * the third parameter of the "out" function actually means 65536UL.
18  * zlib.h must be included before this header file.
