setsockopt is declared as:
        int setsockopt (int socket , int level , int option_name ,
             const void * option_value , socklen_t option_len );

and is used:
        f = TRUE;
        if( setsockopt( h, SOL_SOCKET, SO_REUSEADDR, &f, sizeof f ) )
            return -1;

What is the winsocket prototype?
Maybe you can try and cast &f to (const void *)?

Check that <arpa/inet.h> is included.

Maybe local domain sockets (UNIX paths) are not supported under 
winsocket.
You should try and place the code in the else { ... } section that 
causes this error by:
#if WIN32
        return -1;
#else
        /* code from lines 103-114 */
#endif

Check that <signal.h> is included.


Hope this helps.
