I included it not because I'd seen a need but rather because the  
usage for errno in the page I found via Google  [1]  when I was  
trying to figure out why errno is used the way it is in proxy.c says:
"An application that needs to examine the value of errno to determine  
the error should set it to 0 before a function call, then inspect it  
before a subsequent function call."

I see no reason errno needs to be used at all, though, as getsockopt 
() returns the value directly into the pointer we pass.
