I am not sure how that will work. How do you specify a different value of
system_header for a single location? My understanding is that sysp is for a
whole line_map, so you cannot just change its value for a single location.

We could handle this for each error but that is not ideal either. This would be
trivial if tokens expanded from macros carried two locations around but I guess
that is too expensive, isn't it?
