/*----- A word to the wise ------------------------------------------------*

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