Clang (not currently working)

WARNING: This is outdated, needs to be updated for OpenBSD 6.0 and re-tried.
Using a newer g++ results in linking the new code to a new libstdc++.
Libraries built with the old g++, will still import the old library.
This gives conflicts, necessitating rebuild of all C++ dependencies of the application.
