It now properly handles code that uses curl_free() (since not all versions of
curl have it), and also fixes a few problems when detecting libcurl on MinGW,

automake and friends is not run.

(Let's hope number 2 doesn't break somewhere "out there", if so we can always

from 2003 and added all names from all release notes in the CVS (there is a
slight gap though). I removed names with only first names (Like "Chris" and

AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it (we

AIX 4.3 and it will automatically build with IPv6 support disabled.

--trace, --trace-ascii and --verbose output. I also made the '>' display

-v output.
