   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.
