      the compilation is short-circuited.
   2. When we are mimicking an integrated preprocessor.  Here we use the
      modula-2 'fcpp' to construct a command line for the preprocessor and
      snarf save-temps and dumpdir inputs to try and be consistent.
   3. We can consume a pre-processed modula-2 source.  */
