program. By the way, my new version of cygwin and g++ agreed perfectly with
Tino's response. Also, tests to use a specific "real" address in the bind( )
call didn't change the problem behavior...

my testAccept.exe built on the lastest version of Cygwin runs perfectly on

will have similar problem. Tino reports that he doesn't have any problems on

is down in the new cygwin1.dll but I don't have the time or knowledge to go
digging into that beast. Also, I'm not sure what interaction on my system is
causing the problem. Clearly if Tino can run my testAccept.exe, then there
has got to be something different...

Do you by any chance have any firewall software running on the daemon'ish
machine? ZoneAlaram perhaps?
