This is a port of zlib 1.2.11 to MSDOS/DJGPP.


   zlib 1.2.11 is a free, general purpose data compression/decompression library
   as used in gzip.  All the code is thread safe.


   DJGPP specific changes.
   =======================

   There are no DJGPP specific changes.  Only the usual configuration files have
   been added.  They are located in the /djgpp directory.

   The port has been configured and compiled on WinXP SP3 and Win98SE.  There
   is no guarantee that this may be possible with any other DOS-like OS.  Due
   to the massive use of long file names it will not be possible to configure
   and compile without LFN support.  The port has been compiled using gcc346
   and bnu227b.

   The port has been tested by using it.  I have used them only on WinXP.
   It has worked flawlessly.  I do not konw if this will ever be the case on
   FreeDOS.  I have never used/tested them in that environment.

   To be able to build this port you may need to have LFN support.

   As usual, all djgpp specific files (diffs, README files, etc.) are stored in
   the /djgpp directory.  The sources have been configured to be build in the
   "_build" directory.  If for some reason it does not work for you, delete it
   contents and configure from scratch again.

   Please read the docs to become familiar with this product.


   Here is an extract of the home page showing the user visible changes from
   the last port (zlib 1.2.8) to this one:

-------------------------------------------------------------------------------

Version 1.2.11 has these key improvements over 1.2.10:

     Fix deflate stored bug when pulling last block from window
     Permit immediate deflateParams changes before any deflate input

Due to the bug fixes, any installations of 1.2.9 or 1.2.10 should be immediately replaced with 1.2.11.

Version 1.2.10 has these key improvements over 1.2.9:

     Fix bug in deflate_stored() for zero-length input
     Fix bug in gzwrite.c that produced corrupt gzip files

Version 1.2.9 has these key improvements over 1.2.8:

     Improve compress() and uncompress() to support large lengths
     Allow building zlib outside of the source directory
     Fix bug when level 0 used with Z_HUFFMAN or Z_RLE
     Fix bugs in creating a very large gzip header
     Add uncompress2() function, which returns the input size used
     Dramatically speed up deflation for level 0 (storing)
     Add gzfread() and gzfwrite(), duplicating the interfaces of fread() and fwrite()
     Add crc32_z() and adler32_z() functions with size_t lengths
     Many portability improvements
