default netrc file. We now read and uses HOME _before_ we use getpwuid() to
better allow users to move around HOME to use different .netrc files without
having to rely on even blacker magic.

use as aggressive warning options as possible for the used compiler version.

item 25 is now dealt with using the curlx_ prefix, mentioned in detail here:

that don't have a strtoll() on their own).

linked separately by the application. This function is not provided by the
libcurl API. It can only be accessed by apps if they compile and use this
particular source code.

sockaddr *. This has the added benefit that source files that include
memdebug.h doesn't have to know about "sockaddr".

my_getaddrinfo() (caused a warning by the IRIX MIPSPro compiler). Also
clarified the situation for the 3-arg version of gethostbyname_r() with a huge
comment.

When using it, we now set the include path to better find the devel curl
headers, and we check for the socklen_t type since the curl memdebug stuff
needs it.

to properly work with SOCKS5 proxies. I also included some ascii art describing
the SOCKS5 response, as RFC1928 describes. Jeff provided details in bug
