Dear Elfyn,

Thanks for your prompt response:

The addition of these include files does make gcc -Wall happier, but
it not change the behavior of the program at run-time. Under Cygwin on
my XP box, it still waits many seconds for the connect() to timeout
and then returns with a "Connection timed out" error, instead of
returning after the 2 second alarm with the desired "Interrupted
system call" error.

Eric
