Summary: c-ares compiling on MacOSX 10.3

Initial Comment:
It seems that <arpa/nameser.h> does not include
<arpa/nameser_compat.h> where a lot of macro used by
c-ares are really defined.
I have in the patch also some cast to fix some warning

on my linux nameser_compat.h is there, is included by
nameser.h and has an #ifdef protection to not be included twice.
I don't have a Mac so I based the change on someone else
reports who has a Mac and make me change our own copy of
c-ares. He has compilation problem.
I haven't checked the "cast" change so, forget it :)

I agree with the previous comment. Also, the third argument
to send() is size_t in POSIX (not int):

Why is the cast for socket() needed?

This patch tends to ignore the fact that MacOS X isn't the
only OS out there. I think we'll need configure checks to see
if nameser_compat.h exists, and also, some of your casts
are going to screw up other OSes. Just as one example,
- s = socket(AF_INET, SOCK_STREAM, 0);
+ s = (int)socket(AF_INET, SOCK_STREAM, 0);

s is an ares_socket_t, not an int. On Windows, for example,
it is a SOCKET. By casting it to an int, you might be solving
a problem on MacOS, but you're going to be adding problems
for other OSes.
