accounting for indentation, the code looks like this:

#if defined(HAVE_NETDB_H)
    #include <netdb.h>
    #ifdef HAVE_SYS_TYPES_H
        #include <sys/types.h>
    #endif

    #ifdef HAVE_SYS_SOCKET_H
        #include <sys/socket.h>  //usually included by <netdb.h>?
    #endif
    typedef void* optval_t;
#elif defined(HAVE_WINDOWS_H)
    // if not posix, assume winsock
    #define USING_WINSOCK
    #include <winsock2.h>
    #include <ws2tcpip.h>
    #define SHUT_RDWR 2
    typedef char* optval_t;
#endif

Im guessing that configure did not find netdb.h and if you make
VERBOSE=1, HAVE_NETDB_H will not be in the defines. Can you confirm.

(guess we should have used asio and not tried to write our own cross
platform sockets code)
