I just spent a few hours this week trying to get slang to work with lynx
for DOS, but all I could get was a CGA type screen.  I'ld love to see
what you did that worked?  Did mouse support work with slang?

I would like the patches.  I think that submitting them to the list is
the best way to handle this.  I'll get them from there.

Okay, I have included them here.  There are some known problems:

1) SLtt_add_color_attribute, SLtt_get_screen_size, and SLtt_blink_mode
have not been ported to DJGPP.  

2)  You can't get mouse support working for DOS because there isn't any
available yet.  I think I'll write to John E. Davis <address@hidden>
as he was very helpfull to me when I was having problems with the keypad
interface.  

3) I expected that we would get a "CGA type" screen but I will fix this if
you don't beat me to it.

The patches are against lynx2-7-1ac-0.81 using SLang 0.99.38.  Be sure
that you change the top level makefile so that it uses the -DUSE_SLANG and
-DNO_KEYPAD and remove the flags that refer to NCurses.  

Doug, since you got Lynx to function somewhat with SLang, Let's see your
patches.  

Comments and corrections are welcome.



The patches are below.  I hope they don't break anything but there is so
much ifdef'ing that it's hard for me to tell.  I know that these patches
don't break anything on the dos port.
