I note that while __FILE__, __LINE__, __DATE__, __TIME__ and so on are
macros in C, __func__ is not.  It is a keyword.  So the solution that
Thomas Lindgren proposes seems good.  I would prefer one mechanism that
solves several issues, so I suggest that instead of ?FUNCTION the thing
to have is ?LOCATION
