The correct thing to do is probably to fix include/my_net.h. poll
requires <poll.h>, not <sys/poll.h>. In addition, there should be an
autoconf check for <poll.h>, instead of assuming that because you have
a poll function there is also a poll.h.

The error is because GETHOSTBYNAME_BUFF_SIZE expands to sizeof(struct
hostent_data) and hostent_data is not defined. I think that should be
"struct hostent" instead (I can't find "struct hostent_data" defined
anywhere on the systems I have access to).
