Temporarily, When cross-compiling with gcc 3.0 or later, enable strict aliasing
rules and warnings. Given that cross-compiled targets autobuilds do not run the
test-suite, there is no risk of running code that violates strict aliasing rules
Upon socket address family and length validation failure return ARES_ENOTIMP
in callback again, this is the error code documented in man page and used
mostly all over the library.
Validate socket address family and that the socket address length is appropriate
for the specified family. Failure is reported with ARES_EBADFAMILY in callback.

The purpose of the whole patch was to silence a compiler warning triggered
with GCC 4 on file ares_process.c The specific compiler warning was
'dereferencing type-punned pointer might break strict-aliasing rules'.
A simpler patch will follow to equally silence the warning.
I ran across a small "issue" in your adig example.
It is simply the last part of the NAPTR record, the replacement element,
which is not a string, as currently handled in adig, but a domain name.
If there aren't any sort items to copy, don't bother. Without this
little precaution it would do a malloc(0) which causes undefined
behaviors and is frowned upon by curl's memdebug-system.
ares__read_line returns ARES_EOF when it reaches the end of the
file. This will happen every time when reading to the end of the
HOSTALIASES file. Unfortunately single_domain treats this error as
being fatal.

AIX, at least, does not have sockaddr_storage.ss_family member.
Detect this in the configure logic and use proper #ifdefs in the
ares_process logic.

This helps find compile warnings because they simply break
the build.
To use:
./configure --enable-warnings --enable-werror
