This is a port of libpng 1.2.25 to MSDOS/DJGPP.

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

  The sources require to compile snprintf, so I have taken the appropriate
  files from djgpp CVS source tree.  This is the only change to the sources.
  Apart from this change only the usual files needed for configuration with
  djgpp have been added. That files are stored in the /djgpp directory.
  To configure the package you will have to install the zlib port available at
  ftp.delorie.com and mirrors as:
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlib123b.zip
  or:
    ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/zlib123b.zip
  Of course, you can download a newer version of zlib if available. The zlib
  stored in /current have been compiled with djdev203 and is intented for use
  with Win98SE. The one from /beta is compiled with djdeb204 beta for the use
  with WinXP-SP2.

  Please read the docs to become familiar with this product.
