Subject: write() on closed socket crashes program instead of reporting error

Ok, this time i'll try to be very concise.

Im porting a linux application (a web server). The web server is able to 
manage different connections at a time (max 10 connections).

The problem is this... Imagine tou are downloading a page & in the middle of 
the download you kill (or press the stop button in) the web browser (client 
application). Then, if my web server tries to write() in the (closed | 
killed) socket, instead of reporting an error, the program crashes.

If i run my web server in the bash console of cygwin, it reports an "broken 
pipe" error after crashing.

If I run the web server in a ms-dos console, it dies silently.

the code is like this:

if ((count=write(client_socket,requested_web_page_buffer,length))==-1) {
perror("write");
free_stuff_of_this_connection();
}

In linux, if write fails, perror reports the error and the program frees 
connection & keeps running ok.

In windows (cygwin) if write fails, perror doesn't report anything & program 
crashes.

Im using cygwin1.dll version 1.3.2.

Tnx in advance.
