bsd sockets and gcc 4.0 not all happy in Tiger
I have a project the crossed developed on os x and linux using gcc. Up till gcc 3.3 everything was fine and happy. When tiger came along with gcc 4.0 i started getting weird warnings, and the software has runtime errors with sockets. I have been using gcc_select to get by.
With gcc 4.0 get these build errors.
comm.c: In function 'co1900_new_connection': comm.c:1798: warning: pointer targets in passing argument 3 of 'getsockname' differ in signedness comm.c:1804: warning: pointer targets in passing argument 3 of 'accept' differ in signedness comm.c: In function 'co2000_new_descriptor': comm.c:1863: warning: pointer targets in passing argument 3 of 'getpeername' differ in signedness
1789: getsockname(s, (struct sockaddr *)&isa, &i); 1804: t = accept(s, (struct sockaddr *)&isa, &i); 1863: rc = getpeername(desc, (struct sockaddr *) &sock, &size);
Also in a seperate project under the same situation happened with gcc 4.0 vs gcc 3.3 and bsd sockets.
gcc -c -g -O2 -Wall -DCIRCLE_IPV6 comm.c In file included from sysdep.h:268, from comm.c:14: /usr/include/sys/socket.h:99: error: two or more data types in declaration specifiers

Try changing your declaration of i from "int i" to "unsigned int i"
It is complaining that you are passing a pointer to a signed type when the prototype requires unsigned (or vise versa).
