Sorry, this is a bit confusing.
The line in question comes before preprocessing from which file? Is this file
marked as a system-header? If yes, then why do you expect to get a warning
without -Wsystem-headers? If not, did you edit the processed file? Could we get
the processed file without editing (or at least without removing any
line-markers)?
