In one way, you undercounted: ".cc" was used for about 55k lines of C++

At the same time, it's overcounting to include the libpng, libjpeg,
etc. sources that we have in our repo for convenience. GRacket2 still
depends on those libraries, but it either uses the versions that you
have installed or uses binaries that are downloaded during a build.

I would break it down like this:

             C & C++ that we       C & C++ included       Total
             maintain [*]          for convenience [**]

 GRacket1           455k                190k               645k
 GRacket2           252k                 85k               337k

   * Racket run-time:  227k  (including 15k for GCs)
     GUI (gr1 only):   197k
     MysX, MzCom, SrP:  25k

  ** Image parsers (gr1 only): 105k
     Boehm GC and libffi:       85k

Overall, GRacket2 replaces about 200k lines of C and C++ (on top of Xt,
Win32, and Carbon) with about 30k lines of Racket code (on top of Gtk,
Win32, and Cocoa) plus Cairo and Pango.
