-Why don't we output the token name of the error token in the output?  It is
-explicitly skipped:
-
-      /* Skip error token and tokens without identifier.  */
-      if (sym != errtoken && id)
-
-Of course there are issues with name spaces, but if we disable we have
-something which seems to be more simpler and more consistent instead
-of the special case YYERRCODE.

-We could (should?) also treat the case of the undef_token, which is
-numbered 257 for yylex, and 2 internal.  Both appear for instance in
-toknum:
