These are not extraneous lines. What cpp does is that it no longer puts out
the filename if it has not changed since the last "# n". Makes the C
compiler's scanning a lot faster.

Yeah, you can either run cpp -P from within "imake", or add the *extra*
pattern "# n$".  (I.e. the syntax will be either '# n "filename"' or '# n')
