I can run make repeatedly, and all built files are up-to-date, but the build
system continues to call YACC to build these two files.  The performance hit
isn't huge, but it is annoying.

Octave successfully built.  Now choose from the following:

   ./run-octave    - to run in place to test before installing
   make check      - to run the tests
   make install    - to install (PREFIX=/home/rik/local)

   HG ID for this build is "hg-id-disabled"
