You would think that I would know better..... :-)

It fails to link because of duplicate symbhols that are both in the cpplib
sources and in libiberty. I've attached the make output. I spent a bit of time
trying to fix the problem, but each fix reveled a new problem. Kaveh should do
a build configured with --enable-c-cpplib to reproduce the problems.
