I didn't see the error message this morning when I tried it on my 2000 server. However, you should not ifndef out the code in set_reuseaddr(). The code should do both if available. It does affect wildcard use and it fails to bind other addresses once the wildcard address is bound. I notice that you do a version check in open_socket for versions before XP but fail to allow it to use the set_reuseaddr() since SO_EXCLUSIVEADDRUSE is defined by the compiler. There is no reason for the version check for SO_REUSEADDR but there is for the SO_EXCLUSIVEADDRUSE and that can be done withing the function.
