  43  * There's some clever preprocessor jiggery-pokery going on here, which
  44  * does all the tedious matching up of error names to numbers and severities
  45  * and things.  Quite neat, really.
  46  *
  47  * To actually make the array of error strings *defined*, you should
  48  * predefine the macro error__MAKETABLE.
