This is a port of library PNG 1.6.34 to MSDOS/DJGPP.


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

   As for all binaries and libraries that handle images of any kind, it should
   be noted that files (streams) are *ALWAYS* openend in binary mode with all
   the well known implications on a DOS of WINDOWS OS if the stream comes from
   STDIN and/or STDOUT when these are still connected to the console.
   For the DJGPP port, the "SIGINT" and "SIGQUIT" signals are reenabled when
   the stream is connected to a TTY.
   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/zlb1211b.zip
   Of course, you can download a newer version of zlib if available.

   To compile the source code LFN support is required.  I have build it on
   WinXP and Win98SE but I have never tried to build it on any other OS.


   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 its
   contents and configure from scratch again running the command:
     ..\djgpp\config.bat ../.

   For further information about library PNG please read the info docs and NEWS file.



   The port consists of the usual two packages that have been produced
   using djdev205 and can be downloaded from ftp.delorie.com and mirrors
   as (time stamp 2017-12-24):

     library PNG 1.6.34 scripts, headers, libs and man format documentation:
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/png1634b.zip

     library PNG 1.6.34 source:
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/png1634s.zip


   Send library PNG specific bug reports to <glennrp AT users DOT sourceforge DOT net>.
   Send suggestions and bug reports concerning the DJGPP port to
   comp.os.msdos.djgpp or <djgpp AT delorie DOT com>.


Enjoy.
