I am not against keeping the GSSAPI support in libcurl-minimal. From the
discussion, it sounds like the right thing to do.
Thanks.
But what do you mean by XML-RPC?
I am not aware of any such feature in (lib)curl itself. XML-RPC is usually
implemented in higher-level libraries. If they use the http(s) implementation
of libcurl, they will work on top of libcurl-minimal as well.
Sorry, this is coming
from xmlrpc-c which is using libcurl. As long as
the GSSAPI/GSSAPI delegation features are in libcurl, we should be fine.
