Tony,

I got the same problem after rebuilding. This is related to the "c++
includes not getting searched for correctly?" thread.

As Arnaud has said, the "--with-gxx-include-dir" option is not correct
and does not solve the problem.

As I have mentioned, I think that creating and removing the
${CT_SYSROOT_DIR}/include symlink is also wrong and suggestive that we
are forced to create this because we are making a mistake somewhere
else (binutils? gcc_static/shared_core? libc-startfiles?) and we
should fix that problem first. I believe that if we can solve that
problem, the c++ headers issue will go away.

I will focus on this issue today, and will have some updates later.
