This is a port of library PNG 1.6.26 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:
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:

The port consists of the usual two packages produced using djdev205 that can
be downloaded from ftp.delorie.com and mirrors as (time stamp 2016-11-05):
