with anyway and thus caused picky compiler to warn.

we seem to have nailed that one now!

This is made to prevent compiler warnings.

getaddrinfo() implementation.

These minor changes remove portability issues with the this example and allow
it to run on Win32. Specifically:

* The use of pthread_create() has been replaced by g_thread_create(). This
removes the dependency on the pthreads library. Since this is an example using
GTK+, g_thread_create() is available as it is a part of glibc.

* The CURLOPT_FILE option is now referred to by its "newer name"
CURLOPT_WRITEDATA.

* The use of CURLOPT_WRITEFUNCTION has been added.  As described in the docs,
this avoids the crashes when using a DLL under Win32.

* The output file has been renamed from "/tmp/test.curl" to "test.curl". It's
unlikely that there is a /tmp when in Win32 and other examples in libcurl
write their output files to the working directory.

for finding it using mingw on windows.
I also made the script skip the search for gethostbyname_r and gethostbyaddr_r
when ipv6 is enabled.

we avoid it where possible.

The standards don't actually allow typecasts between data and functions so
some picky compilers warn about this.

We really don't care, and so many other things could've changed to make the
new test interesting anyway.

both the lib and the header present for both defines to be set. If only one
of the files is found, we issue a warning and set no define.
