We should make sure the old command line option still works though and not
simply rename it to the new. That is easily made by simply accepting --krb4 as
well as --krb.

It isn't tested in any kind of test suite, only live by users (and I have no
idea how widespread the usage of those features is).

The only minor problems I have with your patch are:

1) it unconditionally makes name resolving use AI_CANONNAME to getaddrinfo()
    which will add unnecessary reverse lookups to libcurl resolves that have
    no need for them - I would rather like to see that bit get switched on
    dynamicly only when that data is actually needed.

2) + /* FIXME: need to free this eventually */
    + ai->ai_canonname = strdup(he->h_name);

    ... this sounds and looks like a memory leak to me!
