I got concerned after your e-mail, and did a rebuild of everything to
confirm that the build is still working.  It is.

Based on the errors, which are involved with ResourceResponseBase,
ResourceResponse, ResourceRequestBase, and AuthenticationChallenge, I
think it may be that CFNetwork versions of these files were copied
into your build directory one point, and are muddying up the build.  I
used to get this quite frequently when I would switch between
CFNetwork and CURL-based network builds.

My guess is that if you delete the contents of the
WebKitBuild/obj/WebCore/Release_Cairo (and perhaps the DerivedSources
directory as well) it will clear out the invalid binaries so that the
correct CURL-based files will get build, and your build will succeed.

Good luck!
