I promise to test it!
Thanks again,Vladimir Yesin.

i'am trying to start multimple simultaneous UDP listeners for a
multicast packets on a single machine (reuse same address and port
with SO_REUSEADDR)
[...]
with cygwin environment i can't run multiple listerers... bind error:
Address already in use!
Thanks for the report and especially thanks for the testcase. There
is code in Cygwin which skips calls to setsockopt(SO_REUSEADDR) on
systems supporting enhanced socket security. That's necessary to
emulate socket re-binding behaviour more closely to POSIX behaviour.
The problem was that this should have been only called for TCP sockets
but Cygwin accidentally called it for UDP sockets as well. I fixed
that in CVS.
Thanks again,
Corinna
