lynx-dev DOS patch for lynx2.8.4pre.1


From: Doug Kaufman
Subject: lynx-dev DOS patch for lynx2.8.4pre.1
Date: Wed, 6 Jun 2001 21:32:42 -0700 (PDT)

The DOS port has been broken since dev.20. With that version, TXT_W
and TXT_R replaced "w" and "r" throughout the code. This works fine
for unix, but under DJGPP, TXT_W and TXT_R are defined as "wt" and
"rt" respectively, thus overriding the default binary file creation
set by SetDefaultMode. Temporary files are then being created in
truncated form, making it impossible to view graphic files. I found at
least two places that had to be changed to binary to allow graphics to
be viewed, but I worry that there are other problems lurking as files
that had always been binary are now in text mode. Perhaps it would be
best to redefine TXT_W and TXT_R as "w" and "r" respectively under
DJGPP.

The DOS port also lost its false NCURSES define and picked up a
PDCURSES define. This makes it look for pdcurses.h. PDCurses, however
has curses.h, not pdcurses.h. The only reference I could find to
pdcurses.h is in the INSTALLATION file, where users are urged to
rename curses.h to pdcurses.h for the Visual-C++ port. It seems
unreasonable to ask each user to rename the standard files in another
project.

Also note that DJGPP/gcc defines unix, __unix__, and __unix, but not
UNIX.

This patch allows compilation of a functional DOS port, but as I
mentioned above, I think there may need to be other changes in regard
to text vs binary mode.
