changelog of the current development status, as one or more of these problems

+* Using configure --disable-[protocol] may cause 'make test' to fail for
+ tests using the disabled protocol(s).
+
* To get HTTP Negotiate authentication to work fine, you need to provide a
(fake) user name (this concerns both curl and the lib) because the code
wrongly only considers authentication if there's a user name provided.
