my first attempt at a basic description of the certs involvede

land with many warnings and even compiler errors due to missing structs etc

even if user and password are correct

back a 530 after the password is provided, as it isn't necessary because of a
bad user name or password.

decent quote about the define, taken from
http://www.opengroup.org/onlinepubs/007908799/xsh/compilation.html

and if so, define _XOPEN_SOURCE to 500 in an attempt to build with less
warnings (on the 64bit versions)

remains undocumented as this is not the way we recommend)

some general cleanups

already UTF-8 encoded. We check for this case and copy the raw string manually
to avoid the problem. This code can be made conditional in the future when
OpenSSL has been fixed. Work-around brought by Alexis S. L. Carvalho.

the command line

possibly only on some platforms, but it happens on my Solaris 2.7 box and I
don't know anyone else that regularly build curl with krb4 support.

picky warnings

functions (and prevent warnings)
