Unfortunately this ignores the fact that __LINE__ is meaningless
without __FILE__ because there are way too many BUGs in header
files.

Well, it does give us a hint as to which user of the header is
the problem one without going to System.map or objdump.

Even though it is hard on ccache, it is nice to be able to cut
and paste the file name.
