Lynx : unable to connect to remote host --error -possible fix

[Saurabh Gupta <thegage at cyberspace dot org>]

I have a pentium III 550 MHZ
runing windows me : while trying to run lynx in
cygwin. I got an error 

Unable to Connect to Host :lynx.org and the program

terminated . This is inspite of the fact that 
my internet connection was fine and dandy
I spent a weekend tracing the bug and luckily found
it. Therefore this mail for all those facing the same 
problem and for the maintainers of the package to 
hopefully fix it in the standard distribution.
(specifically Corinna Vinschen of cygwin)
(i was told that u are maintaining it in cygwin).



Following is a piece of the log file generated from
lynx -tlog -trace
(the whole file was too long and irrelevant to post here)
(I also had to edit this portion a little bit because 
it had control characters and my email editor got confused)

----end log file ------------------




after spending hours tracking the bug I found that the 
following change in the source file HTTCP.c in the dirctory
/usr/src/lynx2-8-3/WWW/Library/Implementation
OR
<whatever path>/lynx2-8-3/WWW/Library/Implementation/HTTCP.c
and compiling fixed the problem.
Following is the piece of HTTCP.c file that i changed.


   1594
   1595 #ifdef _WINDOWS_NSL
   1596             timeout.tv_sec = 100;
   1597 #else
   1598             timeout.tv_sec = 0;
   1599 #endif /* _WINDOWS_NSL */

/* line 1600 below read like:  
		    timeout.tv_usec = 100000;
before I fixed it. I just increased the timeout
value from 100000 micro second to 900000 microsecond 
*/

   1600             timeout.tv_usec = 900000;
   1601             FD_ZERO(&writefds);
   1602             FD_SET((unsigned) *s, &writefds);




Hope this helps 
Let me know if somebody wants me to send a diff patch
also send me the instructions on how to create it 
I am too lazy to find it out and dont exactly remember
it
Feel free to write to me with any questions.
