Re-reading that very old discussion, and with four years of more experience, I
basically agree with everything you and others say there, including the fact
that a new library is probably not needed. However, I still think that physical
separation, be a directory along-side libcpp or under gcc, helps to clarify
module boundaries. 

Nevertheless, since it turns out I did not need a source-location library to
implement the caret, I am not planning to work on that patch. Getting that
patch approved is likely going to be a bikesheding exercise of epic
proportions. It would be nice if GCC became more modular, but now I don't see
that patch making a huge difference.
