 *
 *          void yyerror(char *message)
 *
 *  Because of the limitations of the routine signature, yyerror relies on
 *  global variables defined by the parser to output additional information
 *  about the error.  Since IDL uses multiple parsers, the global variables
 *  needed depend on which parse is active.  The workaround used here is
 *  that before each individual parse, the pointer variables below will be
 *  set to point to the relevant globals for that parse.  The error routines
 *  can then access the relevant data indirectly through the pointer variables.
