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.
