I tried your below example under 1.5.21 and with a more recent developer
version of Cygwin and the tests run fine in both cases:
$ ./udp-talker.exe localhost blah
sent 4 bytes to 127.0.0.1
got packet from 127.0.0.1
packet is 4 bytes long
packet contains "blah"
If there's a bug, it's not triggered by this test. If it triggers
the problem on your machine, I'd assume the influence of some other
piece of software (firewall, virus scanner, etc)
