Some versions of the BSD getaddrinfo() call do not work with the specific
input of "0" for the servname entry (a segv results).  Since we are making
the call with a dummy port number, the value is actually no important, other
than it should be in range.  Work around the BSD bug by using "1" instead.

	* server.cc (accept_from): Use "1" as the dummy port number.
